What elements make up a basic user interface? If you think about all of the various interfaces you’ve encountered—and don’t just limit yourself to computers—they all have the following elements:

Some way to provide help/guidance to the user.

Some way to allow input of information.

Some way to allow output of information.

Some way to control the interaction between the user and the device.

Think about the interface on a beverage machine. Printed text on the machine will tell you what choices you have, where to put your money, and what to do if something goes wrong. The coin slot is used to input money. There’s often some kind of display to tell you how much money you’ve inserted. And there’s usually a bunch of buttons and levers that let you control the interaction with the machine.

These same kinds of elements make up the basic computer interface. Designing a Graphical User Interface is primarily a process of choosing components that can effectively perform the tasks of input, output, control, and guidance.

In the programs we designed in the earlier chapters, we used two different kinds of interfaces. In the command-line interface, we used printed prompts to inform the user, typed commands for data entry and user control, and printed output to report results. Our GUI interfaces used JLabel s to guide and prompt the user, JTextField s and JTextArea s as basic input and output devices, and either JButton s or JTextField s for user control.

Let’s begin by building a basic GUI in the form of a Java application. To keep the example as close as possible to the GUIs we’ve already used, we will build it out of the following Swing components: JLabel , JTextField , JTextArea , and JButton .

The Metric Converter Application

Suppose the coach of the cross-country team asks you to write a Java application that can be used to convert miles to kilometers. The program should let the user input a distance in miles, and the program should report the equivalent distance in kilometers.

Before we design the interface for this, let’s first define a MetricConverter class that can be used to perform the conversions (Fig. 13.9). For now at least, this class’s only task will be to convert miles to kilometers, for which it will use the formula that 1 kilometer equals 0.62 miles:

Note that the method takes a double as input and returns a double . Also, by declaring the method static , we make it a class method, so it can be invoked simply by

Choosing the Components

Let’s now design a GUI to handle the interaction with the user. First, let’s choose Swing components for each of the four interface tasks of input, output, control, and guidance. For each component, it might be useful to refer back to Figure [fig-swing2-guis] to note its location in the Swing hierarchy.

A JLabel is a display area for a short string of text, an image, or both. Its AWT counterpart, the Label , cannot display images. A does not react to input. Therefore, it is used primarily to display a graphic or small amounts of static text. It is perfectly suited to serve as a prompt, which is what we will use it for in this interface.

A JTextField is a component that allows the user to edit a single line of text. It is identical to its AWT counterpart, the TextField . By using its getText() and setText() methods, a JTextField can be used for either input or output, or both. For this problem, we’ll use it to perform the interface’s input task.

A JTextArea is a multiline text area that can be used for either input or output. It is almost identical to the AWT TextArea component. One difference, however, is that a JTextArea does not contain scrollbars by default. For this program, we’ll use the JTextArea for displaying the results of conversions. Because it is used solely for output in this program, we’ll make it uneditable to prevent the user from typing in it.

Let’s use a JButton as our main control for this interface. By implementing the ActionListener interface we will handle the user’s action events.

Choosing the Top-Level Window

The next issue we must decide is what kind of top-level window to use for this interface. For applet interfaces, the top-level component would be a JApplet . For Java applications, you would typically use a JFrame as the top-level window. Both of these classes are subclasses of Container , so they are suitable for holding the components that make up the interface (Fig. [fig-swing1-guis] ).

Also, as noted earlier, JApplet s and JFrame s are both examples of heavyweight components, so they both have windows associated with them. To display a JFrame we just have to give it a size and make it visible. Because a frame runs as a stand-alone window, not within a browser context, it should also be able to exit the application when the user closes the frame.

Designing a Layout

The next step in designing the interface is deciding how to arrange the components so that they will be visually appealing and comprehensible, as well as easy to use.

Figure [fig-metricgui] shows a design for the layout. The largest component is the output text area, which occupies the center of the JFrame . The prompt, input text field, and control button are arranged in a row above the text area. This is a simple and straightforward layout.

Figure [fig-metricgui] also provides a containment hierarchy , also called a widget hierarchy , which shows the containment relationships among the various components. Although it might not seem so for this simple layout, the containment hierarchy plays an important role in showing how the various components are grouped in the interface. For this design, we have a relatively simple hierarchy, with only one level of containment. All of the components are contained directly in the JFrame .

Figure 13.11 shows the design of the Converter class, which extends the JFrame class and implements the ActionListener interface. As a JFrame subclass, a Converter can contain GUI components. As an implementor of the ActionListener interface, it also will be able to handle action events through the actionPerformed() method.

Figure [fig-converterclass] gives the implementation of the Converter class. Note the three packages that are imported. The first contains definitions of the Swing classes, and the other two contain definitions of AWT events and layout managers that are used in the program.

We have to do all initializing tasks in the constructor. First, we have to set the JFrame ’s layout to FlowLayout . A layout manager is the object that is responsible for sizing and arranging the components in a container so that the elements are organized in the best possible manner. A flow layout is the simplest arrangement: The components are arranged left to right in the window, wrapping around to the next “row” if necessary.

Second, note the statements used to set the layout and to add components directly to the JFrame . Instead of adding components directly to the JFrame , we must add them to its content pane:

A content pane is a JPanel that serves as the working area of the JFrame . It contains all of the frame’s components. Java will raise an exception if you attempt to add a component directly to a JFrame .

The JFrame and all the other top-level Swing windows have an internal structure made up of several distinct objects that can be manipulated by the program. Because of this structure, GUI elements can be organized into different layers within the window to create many types of sophisticated layouts. Also, one layer of the structure makes it possible to associate a menu with the frame.

Finally, note how the Converter frame is instantiated, made visible, and eventually exited in the application’s main() method:

It is necessary to set both the size and visibility of the frame, since these are not set by default. Because we are using a FlowLayout , it is especially important to give the frame an appropriate size. Failure to do so can cause the components to be arranged in a confusing way and might even cause some components to not appear in the window. These are limitations we will fix when we learn how to use some of the other layout managers.

Inner Classes and Adapter Classes

In this section we introduce two new language features, inner classes and adapter classes , which are used in the main() method shown above to handle the closing of the Converter application’s window when the program is exited:

This code segment provides a listener that listens for window closing events. When such an event occurs, it exits the application by calling System.exit() .

The syntax used here is an example of an anonymous inner class . An inner class is a class defined within another class. The syntax is somewhat ugly, because it places the class definition right where a reference to a window listener object would go. In effect what the code is doing is defining a subclass of WindowAdapter and creating an instance of it to serve as a listener for window closing events.

Anonymous inner classes provide a useful way of creating classes and objects on the fly to handle just this kind of listener task. The syntax used actually enables us to write one expression that both defines a class and creates an instance of it to listen for window closing events. The new subclass has local scope limited here to the main() method. It is anonymous, meaning we aren’t even giving it a name, so you can’t create other instances of it in the program. Note that the body of the class definition is placed right after the new keyword, which takes the place of the argument to the addWindowListener() method. For more details on the inner and anonymous classes, see Appendix F.

An adapter class is a wrapper class that implements trivial versions of the abstract methods that make up a particular interface. (Remember from Chapter 4 that a wrapper class contains methods for converting primitive data into objects and for converting data from one type to another.)

The WindowAdapter class implements the methods of the WindowListener interface. When you implement an interface, such as ActionListener , you must implement all the abstract methods defined in the interface. For ActionListener there’s just one method, the actionPerformed() method, so we can implement it as part of our applet or frame class. However, we want to use only one of the seven methods available in the WindowListener interface, the windowClosing() method, which is the method implemented in the anonymous inner class:

The WindowAdapter is defined simply as

Note that each method is given a trivial implementation (). To create a subclass of WindowAdapter , you must override at least one of its trivially implemented methods.

Another way to manage the application’s window closing event is to define a subclass of WindowAdapter :

Given this class, we can then place the following statement in Converter ’s main() method:

This is somewhat more familiar looking than the inner class construct. If you prefer this way of handling things, you can use this method in place of the inner classes here and in other examples.

GUI Design Critique

Figure 13.13 shows the converter interface. Although our basic GUI design satisfies the demands of input, output, control, and guidance, it has a few significant design flaws.

First, it forces the user to manually clear the input field after each conversion. Unless it is important that the user’s input value remain displayed until another value is entered, this is just an inconvenience to the user. In this case, the user’s input value is displayed along with the result in the JTextArea , so there’s no reason not to clear the input text field:

A second problem with our design is that it forces the user to switch between the keyboard (for input) and the mouse (for control). Experienced users will find this annoying. An easy way to fix this problem is to make both the JTextField and the JButton serve as controls. That way, to get the program to do the conversion, the user can just press the Enter key after typing a number into the text field.

To give the interface this type of control, we only need to add an ActionListener to the JTextField during the initialization step:

A JTextField generates an ActionEvent whenever the Enter key is pressed. We don’t even need to modify the actionPerformed() method, since both controls will generate the same action event. This will allow users who prefer the keyboard to use just the keyboard.

Given that the user can now interact with the interface with just the keyboard, a question arises over whether we should keep the button at all. In this case, it seems justifiable to keep both the button and the text field controls. Some users dislike typing and prefer to use the mouse. Also, having two independent sets of controls is a desirable form of redundancy. You see it frequently in menu-based systems that allow menu items to be selected either by mouse or by special control keys.

Another deficiency in the converter interface is that it doesn’t round off its result, leading sometimes to numbers with 20 or so digits. Develop Java code to fix this problem.

Give an example of desirable redundancy in automobile design.

Extending the Basic GUI: Button Array

Suppose the coach likes our program but complains that some of the folks in the office are terrible typists and would prefer not to have to use the keyboard at all. Is there some way we could modify the interface to accommodate these users?

This gets back to the point we were just making about incorporating redundancy into the interface. One way to satisfy this requirement would be to implement a numeric keypad for input, similar to a calculator keypad. Regular JButton s can be used as the keypad’s keys. As a user clicks keypad buttons, their face values—0 through 9—are inserted into the text field. The keypad will also need a button to clear the text field and one to serve as a decimal point.

This new feature will add 12 new JButton components to our interface. Instead of inserting them into the JFrame individually, it will be better to organize them into a separate panel and to insert the entire panel into the frame as a single unit. This will help reduce the complexity of the display, especially if the keypad buttons can be grouped together visually. Instead of having to deal with 16 separate components, the user will see the keypad as a single unit with a unified function. This is an example of the abstraction principle, similar to the way we break long strings of numbers (1-888-889-1999) into subgroups to make them easier to remember.

Figure [fig-metricgui2] shows the revised converter interface design. The containment hierarchy shows that the 12 keypad JButton s are contained within a JPanel . In the frame’s layout, the entire panel is inserted just after the text area.

Incorporating the keypad into the interface requires several changes in the program’s design. Because the keypad has such a clearly defined role, let’s make it into a separate object by defining a KeyPad class (Fig. 13.15). The KeyPad will be a subclass of JPanel and will handle its own ActionEvent s. As we saw in Chapter 4, a JPanel is a generic container. It is a subclass of Container via the JComponent class (Fig. [fig-swing2-guis] ). Its main purpose is to contain and organize components that appear together on an interface.

In this case, we will use a JPanel to hold the keypad buttons. As you might recall from Chapter 4, to add elements to a JPanel , you use the add() method, which is inherited from Container . (A JApplet is also a subclass of Container via the Panel class.)

As a subclass of JPanel , the KeyPad will take care of holding and organizing the JButton s in the visual display. We also need some way to organize and manage the 12 keypad buttons within the program’s memory. Clearly, this is a good job for an array. Actually, two arrays would be even better, one for the buttons and one for their labels:

The label array stores the strings that we will use as the buttons’ labels. The main advantage of the array is that we can use a loop to instantiate the buttons:

This code should be placed in the KeyPad() constructor. It begins by instantiating the array itself. It then uses a for loop, bounded by the size of the array, to instantiate each individual button and insert it into the array. Note how the loop variable here, k , plays a dual role. It serves as the index into both the button array ( buttons ) and the array of strings that serves as the buttons’ labels ( labels ). In that way the labels are assigned to the appropriate buttons. Note also how each button is assigned an ActionListener and added to the panel:

An important design issue for our KeyPad object concerns how it will interact with the Converter that contains it. When the user clicks a keypad button, the key’s label has to be displayed in the Converter ’s text area. But because the text area is private to the converter, the KeyPad does not have direct access to it. To address this problem, we will use a Java interface to implement a . In this design, whenever a KeyPad button is pressed, the KeyPad object calls a method in the Converter that displays the key’s label in the text area.

Figure [fig-p493f1] provides a summary of the callback design. Note that the association between the Converter and the KeyPad is bi-directional. This means that each object has a reference to the other and can invoke the other’s public methods. This will be effected by having the Converter pass a reference to itself when it constructs the KeyPad :

Another important design issue is that the KeyPad needs to know the name of the callback method and the Converter needs to have an implementation of that method. This is a perfect job for an abstract interface:

The KeyPad can interact with any class that implements the KeyPadClient interface. Note that the KeyPad has a reference to the , which it will use to invoke the keypressCallback() method.

The implementation of KeyPad is shown in Figure 13.17. Note that its constructor takes a reference to a KeyPadClient and saves it in an instance variable. Its actionPerformed() method then passes the key’s label to the KeyPadClient ’s callback method.

Given the KeyPad design, we need to revise our design of the Converter class (Fig. [fig-p493f1] ). The Converter will now implement the KeyPadClient interface, which means it must provide an implementation of the keypressCallback() method:

Recall that whenever the KeyPad object calls the keypressCallback() method, it passes the label of the button that was pressed. The Converter object simply appends the key’s label to the input text field, just as if the user typed the key in the text field.

The complete implementation of this revised version of the interface is shown in Figure 13.18 on the next page. The appearance of the interface itself is shown in Figure 3.19.

Figure 3.19 shows that despite our efforts to group the keypad into a rectangular array, it doesn’t appear as a single entity in the interface itself, which indicates a layout problem. The default layout for our KeyPad (which is a JPanel ) is FlowLayout , which is not appropriate for a numeric keypad that needs to be arranged into a two-dimensional grid pattern, which is the kind of layout our design called for (Fig. [fig-metricgui2] ).

Fortunately, this flaw can easily be fixed by using an appropriate layout manager from the AWT. In the next version of the program, we employ the java.awt.GridLayout , which is perfectly suited for a two-dimensional keypad layout (Section 13.7.2).

The lesson to be learned from this example is that screen layout is an important element of an effective GUI. If not done well, it can undermine the GUI’s effort to guide the user toward the appointed tasks. If done poorly enough, it can even keep the user from doing the task at all.

19. Supply chain management system

This is one of the interesting Java projects. Supply chain management refers to the management of businesses interconnected over a network. It includes a whole range of management procedures like handling, storage, and movement of raw materials, inventory, and transporting finished goods from the source to its final destination.

This project aims to smoothen the supply chain management process by closely monitoring the dealers and clients and continually tracking the products through the different points in the supply chain. Using this application, a company can directly communicate with its clients, obtain the product requirements, manufacture the product to fit those requirements, and finally ship it off to the client. 

This project uses JSP, JDBC, and HTML for the front-end and MS Access as the back-end database. It is a web-based application that will automate the system of communication between the management or admin, dealers, and clients of the company. There are three modules in this application:

• Admin module – The Admin uses this module to check information on the manufactured products, newly launched products, and products that must be delivered to the clients.
•  Dealer module – This module keeps track of all the essential information concerning the dealers, particularly the record of items. Dealers can generate and update the item list for a product using this module. 
• Client module – The client uses this module to provide the necessary specifications of a product. The client feedback is processed through this module and forwarded to the Admin. 

By using this application, the clients can directly convey their product requirements to the manufacturer, who then contacts multiple vendors to acquire the necessary resources for making the product. The dealers usually create a list of items as per the product information provided to them, after which the manufacturer selects the materials that best fit the specifications given by the client.

Then, the selected list of items is forwarded to the inventory department for processing, after which the manufacturing begins. Once the production is complete, the accounts department calculates the raw materials costs and manufacturing costs to generate the total bill. Finally, the product, along with the invoice, is shipped to the client. The client is free to offer feedback on the received product.

20. Virtual private network

VPN is one of the trending java projects. The goal of building this virtual private network (VPN) is to extend a private network across a public domain (for example, the Internet). A VPN is created by setting up a point-to-point virtual connection via traffic encryption, dedicated connections, or virtual tunneling protocols.

There are three interconnected modules in this VPN project: 

• Administration module – This module monitors all the office operations and manages the staff details. 
• Marketing module – This module handles everything related to the marketing operations of the software application.
• Training module – This module manages all the technical operations like software testing, networking, call center, and J2EE training.

Confidentiality, authentication, and data integrity are the three core elements of this VPN security model. The other pivotal features of this application are:

• It allows for the addition of new clients, a feature better known as “scalability.” This feature allows a company/organization to accommodate new clients in the network as it expands. 
• It uses a remote backup server to prevent the system from failing due to sudden crashes. Since a VPN handles a large volume of files that are created every day, it is crucial to have a remote backup server to process all the requests coming from the client to the server and vice-versa.
• It uses a remote monitoring system to keep track of the activities of every client or individual connected to the VPN. This ensures that the privacy and security of the network remain intact.
• As is true of all VPNs, this VPN application, too, has the provision for certification in the system. When two or more LAN (Local Area Network) systems interact, certification is mandatory to protect the system’s security. 
• It triggers and sends acknowledgment signals to notify clients of successful data transfer (whether or not the data has successfully reached the desired destination).

21. Customer relationship management system

The CRM system is designed with the aim to assist businesses in keeping digital records of all customer interactions. If you are considering Java projects for final year , this project is the best choice. It provides the source code for Java and uses the Spring framework. The project requires sound knowledge of MySQL, JSpring framework, Java database connectivity, and HTTP. 

This application aims to help businesses improve customer satisfaction by providing access to past, present, and potential customer data and help maintain them efficiently. CRM systems operate by collecting customer data from various sources like the company’s website, live chats, social media, telephone, emails, etc.

This mini project in Java is an open-source desktop application consisting of 3 main roles — admin, user, and employee. The primary user is the admin, who can change product-related details like adding, deleting, and updating. They can also change the FAQs and keep track of user history, employee details, complaints, inquiries, etc. 

Employees can access complaints, inquiries, and product lists and also keep profiles updated with information collected from emails, calls, and chats. This reduces the time to resolve customer issues, enhancing the overall customer experience.

Conversely, users can view product details, raise complaints, view FAQs, and make service/product-related inquiries.

Some advantages of the CRM system are:

• Build a robust and secure CRM application.
• Drive customer engagement
• Contains records of users, employees, complaints, resolutions, and more.
• Provide error-free application

22. Mobile tracking system

Of all the Java project topics , this one ranks among the top useful application ideas. Mobile phones are no longer used for luxury but have become a necessity in the modern world. With violent incidents becoming commonplace, safety concerns have increased manifold in the last couple of years. This is where Java mini projects like this come in handy. 

As the name suggests, the mobile tracking system tracks the present location of a user’s phone. This web application is developed on MySQL database using PHP. It constantly updates the location of the chosen device every five seconds through a central tower. The system sends the server the mobile ID and location, along with the time the device was present at the location.

The system has to be installed in the chosen device, following which each device is assigned a unique ID. This ensures you can track the desired mobile phone from anywhere, anytime. This project aims to boost security and consists of two primary components: the web application (serves as the admin) and mobile tracking software installed on the phone to be tracked. 

Although Java is a relatively new programming language ( it was launched in the early 1990s ), it has created a unique niche in the IT industry. Java is the driving force behind some of the largest organizations, including Airbnb, Uber, eBay, Pinterest, Groupon, Spotify, Intel, Symantec, TCS, Infosys, Wipro, Flipkart, and TripAdvisor, to name a few.

As an OOP language, Java has a modular structure, making solving complex problems significantly easier. Thus, programmers can write reusable codes with Java, enhancing the development process. Additionally, Java offers various features, such as polymorphism, abstraction, inheritance, and encapsulation, that further simplify the code-writing process. Easy to program and run, Java-based applications can be developed to operate on one computer as well as multiple client and server systems within a network.

The five main reasons for Java’s popularity are:

• Platform independence – Java runs on the WORA (Writing Once, Run Anywhere). A Java code is compiled into an intermediate format (a.k.a. bytecode), which is then executed in the JVM (Java Virtual Machine). So, any system running a JVM can execute Java code. Furthermore, JRE (Java Runtime Environment) is compatible with all three operating systems – Linux, macOS, and Windows.
• Multi-threaded – Java has inbuilt multithreading capabilities, which means that you can develop highly interactive and responsive apps with multiple concurrent threads of activity using Java.
• Object-oriented – Java is a purely object-oriented language. Inspired by C and C++, Java extends the functionality of these languages to become a pure object-oriented programming language. Abstraction, encapsulation, inheritance, and polymorphism are some of its core OOP features. 
• Secure – When it comes to safety, Java incorporates a host of safety features into the runtime systems, including runtime checking and static type-checking at the time of compilation. With these features in place, it is pretty challenging to hack into a Java application from an external source.
• Robust – Java leverages a simple memory management model reinforced by automatic garbage collection. Since Java objects do not require external references, Java code is robust. Besides, it also encourages developers to adopt productive programming habits for developing secure and reliable applications. The more you experiment with different java projects, the more knowledge you gain.
• Open source – Java’s position as the second most trending programming language worldwide ( IEEE Spectrum ) in 2023 primarily rests on it being freely available for use; in other words, it is open source. This makes it ideal for developers and programmers of various competencies looking to build apps of their own. They can even access the latest versions of Oracle JDK and Open JDK free of charge through the Java Development Kit.
• API rich – Consisting of approximately 52 keywords, Java boasts a rich and extensive API (Application Programming Interface). Thus, making projects in Java is easy, with a multitude of methods available for use in any program directly. Developers can accomplish any task with Java API methods, whether handling output input, networking, processing XML, or connecting to databases.
• Community backup – Java’s robust and active community is among the many reasons for its continuing popularity. The Java Community, Stack Overflow, and Java in General are some of the top communities where developers and beginners alike can find assistance when faced with a problem. If you are developing core Java projects or seeking project ideas for Java, you can find extensive and reliable support on these websites from expert developers.
• Documentation support – Another factor contributing to Java’s immense popularity is its detailed documentation feature. Javadoc, a well-documented guide, provides solutions to developers who face problems while coding any application or program.
• Development tools – In addition to frameworks, integrated development environments (IDE), and profilers, Java has an arsenal of various automation, debugging, and editing tools. Java has tools for every type of development project along with various stages of development. Different projects in Java require the use of different tools. These include Maven for building applications, Jenkins for integration and delivery, JIRA for bug tracking and planning, and Splunk for monitoring, to name a few.
• User-friendly – Java offers an easy learning curve with its simple English syntax and use of minimum special characters. This makes it easy for beginners and professionals to master this language. Basic knowledge of programming languages like C and C++ is all that is needed to learn Java and build projects using Java later. Resources are readily available online on various websites, mostly for free.

“Our world, moved by Java”, Take a moment to contemplate this phrase. Java is one of the most commonly used programming languages. It is also used as the server-side language for most of the back-end development tasks, like those concerning Android development and Big Data. Java is also used for desktop computing, other mobile computing, games, and numerical computing. The popularity of Java is further evidenced by 90 per cent of all Fortune 500 companies using Java. In this article, we’ll be looking at 15+ exciting Java project ideas/topics for you to explore and practice.

Any layman can be a good developer, no matter if you possess a certain gene code to accomplish this or not. That being said, putting in the effort and harbouring the correct mindset is inevitable to accomplish this. Creating Java projects will assist you to hone your skills on real-life projects and amplify your spirit as a developer. This is the sole way to know if you own a pragmatic grasp of the theory you’ve learned. Functioning on these Java projects will let you equip yourself for a job.

The theoretical knowledge that you have is not of utmost importance, employers are interested in how you are able to translate the knowledge in a practical setup. You should create a portfolio of the tasks you have accomplished so far. So, when you interview for the role of developer, you will have solutions, code, apps, and projects, to exhibit to the recruiters. The portfolio will emphasize your strong points and recognize flaws that need modification.

Confused about your next job?

Reasons why software companies choose Java for developing enterprise applications:

• The software industry adopted Java as it made development a pleasure, resolved problems with distribution, and lessened the pang of continuously porting across platforms.
• As Java is an object-oriented language, it is huge and secure. Java programs are composed independently of the platform in bytecode language, which lets the same program work on any machine that is equipped with JVM. It is a realistic and practical approach to software design. Java objects envelop data and behaviour so that code can be used again, thereby making the process of testing and troubleshooting easier.
• Java’s popularity grew when people learned how Java could solve their hardships on servers – making productivity, execution, and scalability reach new levels.
• Java has demonstrated its supremacy over other languages from server-side scaling of multi-tier architecture to internet distribution of software, to the cloud-native deployments, to taking benefit of continuously upgrading hardware architectures and a whole lot more.

Here’s a list of ideas for beginners to try with Java

With the growing trend of hacking attacks, everyone should create different and complex passwords for their diverse accounts to keep them secure. Remembering every password is not humanly possible and noting it down somewhere is not a wise idea. Hence, people take the help of Password generators to create strong and complex passwords for their accounts. To generate such functionality all by yourself, you can take advantage of the function that java offers. Whenever a user is developing an account on a new website, you can use that program to develop a password. To take the safety of the password a notch above, you can enforce such functionality so that it saves passwords in encrypted form. To incorporate this, you need to study the fundamentals of Cryptography and Java Cryptography Architecture.

The idea of this project is to create a core java project that can accumulate the viewpoint of a targeted audience of a survey through the Internet. Based on that, the app can send the targeted audiences promotional emails and can launch online surveys. Any business can make use of this type of software to assemble feedback regarding the services or products they offer. We can build such functionality so that only registered customers can cast their responses. The main attributes of the app should be:

• The apps are programmed in a way that they should be compatible with various databases like SQL and NoSQL.
