Java is a relatively old language in the world of programming, but in recent years it has maintained its position in the IT industry. Interestingly, Java plays a vital role in large organizations such as Airbnb, Uber, eBay, Pinterest, Groupon, Spotify, Intel, Symantec, TCS, Infosys, Wipro, Flipkart, and TripAdvisor.

Why is the Java programming language so popular?

The most important reasons for the popularity of the Java language are the following:

• Independent of OSCO: Java programming language codes are compiled into a particular type of machine language code called bytecode and then executed on a Java virtual machine. Hence, any system running a Java virtual machine is capable of performing Java code. In addition, the Java runtime environment (JRE) is compatible with Linux, Mac, and Windows operating systems.
• Multi-threading: Java has built-in multi-threading capabilities; it can build interactive applications that can run multiple strings simultaneously.
• Object Orientation: Java is an object-oriented language and, like the Ciplus-Plus programming language, provides good support for object orientation. Abstract, encapsulation, inheritance, and polymorphism are some key features of the object-oriented programming paradigm that Java supports.
• Security: Regarding safety, Java provides a robust set of security features for developers, including runtime and static compile time. Despite these features, hacking Java applications is more complex than other languages.
• Powerful: Java uses efficient memory management and an automated garbage collection mechanism. Since Java objects do not require external references, Java code works well. Java recommends that developers use standard, built-in programming models to develop secure and reliable applications.

Standard Java applications

Java is a universal programming language and can build a variety of applications. Typically, developers use Java to make the following applications:

Software tools

• Java is the backbone of various software applications and is widely used in connection with open source and commercial software projects. Eclipse, IntelliJ IDEA, BlueJ, JDeveloper, and NetBeans IDE are some of the most popular integrated development environments for programmers to build applications and tools using the Java language.

Android applications

• Java provides developers with a wide range of libraries and software modules for building Android applications. Eclipse Integrated Development Environment is one of the most widely-used development environments for building Android applications using Java. Kathleen is the second option for building Android applications, which, of course, is based on the Java virtual machine and is modeled on  Java in its design.

Web applications

• Java is an excellent choice for developing web applications because of its flexibility, reliability, and high performance. Java supports web applications via JSP and Servlets. Developers can use Java to build dynamic websites.

Scientific applications

Regarding science programs, Java performs better than C++ because it offers a comprehensive set of tools for synchronous programming. Sustainability, security, and structuredness are prerequisites for scientific applications, and Java supports all of these features when building scientific applications.

Exciting ideas for building Java projects

Now that we have reviewed the most important features of Java and its applications, it is time to introduce Java projects. If you are a final year student of computer science or have just learned the basics of the Java programming language, this list gives you some great ideas for building projects.

 1. Plane ticket reservation system

One of the exciting ideas in this field is to build a plane ticket reservation system, a Java-based project. A passenger request processing system includes inventory, fares, e-ticketing operations, and online transactions. The main features of the airline ticket reservation system are as follows:

•  Book and cancel plane tickets.
•  Notification of flight cancellations.
•  Offer ticket booking offers at lower rates.
•  Informing customers about flight routes.
•  Prompt response to customers.
•  We are maintaining passenger records and daily reporting of financial transactions.
•  Provide information about hotels and tourist places according to the ticket purchased by the customer.

The integrated airline ticket reservation must redesign in the form of an architecture to allow additional modules and capabilities to be added to the program. The point to keep in mind is that the program is designed to be up to date with changes in the business world and specific circumstances. To be more precise, it is based on a dynamic design. In this regard, the Vehicle Recognition Suite VRS software suite includes four critical modules: user registration, login, booking, and cancellation, which is a good guide in this field and provides good information to programmers.

2. Course management system

As the name implies, it is a classroom management system that should be able to provide offline and online services so that educational institutions can use them without any problems. The primary goal of this project is to facilitate integrated interaction between students and educators in schools, colleges, and universities regarding submitting projects, assignments, dissertations, and receiving feedback from educators. Such a project should have the following three interconnected modules:

• Admin Module: This module manages administrative functions such as account creation for students and educators, curriculum development, heading, staff management, payroll, and more. This module is connected to two other modules.
• Student Module: This module is designed for student use. They can log in to view their training courses, submit their projects, receive instructor feedback, and more.
• Instructor Module: This module is for instructors who will log in to their account and review the projects submitted by the students, communicate with them, and guide them.

3. Data visualization software

Data visualization is an industry-wide application widely used in data science, business intelligence, and business analytics. Data visualization is the visual representation of data in a graphic or graphical format. To build this project, you must have sufficient knowledge about machine learning and data mining. Among the features that you should pay attention to when developing this project are the following:

• I am providing information hidden in the heart of the data through graphic or visual representation to people who do not have technical knowledge.
•  Explore complex datasets, extract information from them, and turn it into credible insights.
•  It is Practicality and design based on aesthetic principles.

The best part of the project is the software features and functions that you need to spend enough time designing. The Data visualization software aims to show the relationship between nodes in a network. The above software must be able to work with a mouse or trackpad to find the location of data.

4. Electricity billing system

The main focus of this Java project is to digitize the electricity billing system to make it more integrated, accessible, and efficient. This software calculates the amount of consumption in a certain period and the amount of money that must pay for the amount of use. The essential features of a simple electricity billing system are as follows:

• It is a  High performance and accurate calculation of prices in different periods.
• It is the Ability to share data seamlessly between the electricity office and customers.
•  Implement security measures and controls to protect software against hacking.
• It is the Ability to pay bills by connecting to the banking system.
• It is the Ability to send text messages to customers.
•  Provide detailed information regarding the amount of consumption in different seasons.

Unlike the traditional billing system, this software does not require much workforce to manage the billing process. In the more advanced model, the software should be able to receive consumption information read by the reader.

5. Electronic health care management system

One of the community’s most attractive and practical ideas is to build an “electronic health management system.” The e-Health Care Management System is a web-based project that seeks to provide effective management of the data of the staff of the health department and the medical data of the patients admitted to the hospitals and clinics. If you are planning to write a professional project, you should use data mining techniques in this regard. A simple e-healthcare management project consists of management and customer modules. The management module includes health care wards, doctors, nurses, and staff. The client module focuses on patients and patient information. The key features of an e-healthcare management system are as follows:

•  Establish a line of communication between physicians and patients.
•  I was calculating the percentage of use of hospital resources such as laboratory equipment, the occupancy rate of beds to free beds, monitoring of prescribed and consumed drugs, etc.
•  Back up data to retrieve information in specific situations.
•  An e-healthcare management system is designed to overcome the challenges of a traditional healthcare management system so that hospital staff can provide services more quickly.

   6. Email client software

Why not use our skills to develop an efficient Java project for email management? This project is an email application designed to send and receive emails. This project uses sockets, communication protocols for sending and receiving emails, and Java Mail API. The two main protocols to be used in such a project are SMTP and POP3.

Typically, a regular email client software provides email services in conjunction with Hotmail, Yahoo, and Google services. Because these systems use port 80 of the HTTP protocol to access email, the project is not intended to be a secure email management software, especially when sensitive or confidential messages are to be sent. This project is more suitable for educational purposes or sending and receiving emails among a group of friends.

 7. Library management system

This software project in Java can be implemented based on the MS Access database so that the implementation process is not complicated. The above project manages and organizes books through an integrated computer system in schools or libraries. Library management software allows librarians to perform the typical daily tasks of a library.

In a traditional library management system, everything is done manually. All library operations and records are done in writing, including the number of books, book genre, book name, records of students who received or returned the book, etc. This process requires considerable time. The above example is an excellent choice if you are looking for an idea for a project lesson.

Your proposed project should address all the challenges associated with a traditional library management system. Because all library records are stored and managed in a computer database, the dependency on manual record-keeping is eliminated. The software includes several modules, each of which contains specific library operations.

With this software, librarians and students do not need to search the entire library to find a book. They can enter the name and author of the book, and the system displays a list of all available books based on the phrase they have entered.

8. Network packet monitoring tool

Network packet monitoring is a network packet analyzer software used to monitor network traffic. The project handles the process of monitoring packets exchanged on a network. More precisely, it is something like WireShark that network experts use to evaluate network performance. Using the above software, the administrator can record network packets and analyze the data received and sent from/to the network. This software must be able to monitor packets being sent between two or more nodes.

The purpose of designing the above project is to determine the runtime rules to identify suspicious activities going on around the system programs and processes. Unlike standard network hosts, which only track forwarded traffic, the program must record each packet, parse it, and provide a comprehensible output to the network administrator. The key features of this software include the following:

•  Full-time network monitoring.
•  Record packages in real-time.
•  Advanced Analysis of Protocols.
• Complex network analysis.
•  Closed-level automated analysis.
•  Decrypt packages.

9. Online bank management system

This project focuses on the development of an online banking system. The main goal is to create an online banking platform accessible from anywhere. Customers do not need to visit bank branches to perform routine banking operations such as withdrawing money, transferring money, inquiring about balances, etc.

Physical visits to bank branches are time-consuming, and you have to wait in line for a long time. These issues can address by developing an online banking system that provides customers with integrated and fast banking services. To use this application software, the user must register in the system. To do this, the user must create a unique username and password to log in securely. A simple online banking management program provides customers with the following services:

• Customers can view their account details, such as account type, current balance, interest rates on existing loans, credit/debit statements, etc., from anywhere.
•  Customers can check their transaction history, including the transaction time, type, and amount.
•  View the amount of cash deposited or cash withdrawn along with the date of deposit/withdrawal.

10. Online medical management system

Another web-based project is designed to establish a direct line of communication between physicians and patients. With this application, patients can book online appointments with their favorite doctors, and doctors can provide health suggestions, electronic prescriptions, etc., and view patient medical records, laboratory reports, and more. In the professional world, the project is also known as a virtual medical home.

In conventional health care systems, all medical management operations are done manually, which causes problems. This problem is more acute in remote areas that lack proper medical infrastructure, qualified specialists, and advanced medical equipment. In addition, there are no rules for recording and storing medical data. An online medical management system can solve the above problems by directly linking physicians and patients.

This program has two modules, Management, and Physician. The management module is for comprehensive and online software monitoring, and the physician module allows specialists to interact with patients. Doctors and patients can access the services provided by this program from anywhere through the Internet.

11. Online test management system

Another exciting project is Java, which focuses on conducting and managing online exams. The program creates an online chat platform comprising various sections such as holding classes, chat rooms, testing, and viewing test results. The program allows school administrators and instructors to prepare for online exams most simply by designing a user-friendly environment. In this project, you prepare a comprehensive online platform for managing exams so that people can answer the questions and see their scores at the end.

It is also possible to implement team competitions in professional programs. For example, instructors can create n participating teams for the competition and specify n rounds for the stage so that participants can answer questions within the allotted time.

Each team’s scores are automatically updated. If a team fails to answer a question or gives a wrong answer, it will receive a negative score. The teams with the lowest score will be eliminated, and the remaining units will advance to the next round to be declared the final winner. Master’s degree students in software engineering can, with a little more work on this project, submit it as a final project to the relevant professor.

12. Online polling system

An online poll system is an online platform that collects the opinions of participants in an online poll. Any organization in any industry can use this program to conduct online surveys to obtain the necessary information from the target audience. The app can run online polls and send email notifications.

In the poll program, only users who the admin has authenticated can vote and express their opinion on a particular topic. Once users have submitted their comments, the software receives and records the information. They then categorize the comments received for each option and display the result after the poll expires. In advanced examples, polling systems do not allow one person to participate in the survey twice. The main features of a simple online poll system are as follows:

•  In Java, it uses the MySQL server database to record information.
•  It can hide the identity of users/voters and thus collect all information confidentially.
•  It has the feature of inserting comments for each user so that one person can not post additional comments many times.
•  It is possible to use the software anywhere at an affordable cost.

Because polls are conducted online, the data collection process is faster, and the costs associated with conducting surveys are reduced.

13. Supply chain management system

Supply chain management refers to the monitoring of business activities and online tracking of the status of goods and shipments. This process involves a wide range of management procedures such as the movement, storage, and movement of goods, inventory, and transportation of goods from origin to destination.

This project simplifies the process of monitoring the delivery of goods by closely monitoring vendors and customers and continuously tracking products through different parts of the supply chain. Using this software, a company can communicate directly with customers, identify product needs, produce the product according to customer needs, and send it to customers.

A simple supply chain management project uses JSP, JDBC, and HTML for Frontend and Microsoft Access as a database. This web application provides the most external communication between the company’s management, salespeople, and customers. Such a project consists of three main modules:

• Management Module: The manager uses this module to review information about manufactured products, newly produced products, and products that need to be delivered to customers.
•  Vendor Module: This module records all the necessary information about vendors. Vendors can use this module to generate and update a list of items for a product.
• Customer Module: The customer uses this module to view a product’s specifications and provide management feedback.
