If you are currently a final year student, job seeker or professional looking for a job change, having an amazing portfolio with a couple of beginning java projects will give you an added advantage to shine and get shortlisted for interviews. As a Java developer, one should have extensive knowledge of Java fundamentals, and coding principles like object oriented programming OOPs, Data Structures, Mobile/Web Development, API development etc as per requirement and interest. Also, it is important to practice these skills by building Java projects ideas based applications to solve a variety of real-world problems.
Based on your experience and interest you can start by building a basic application like a number guessing game to build any complex application to solve a problem you faced.
Let’s discuss Topics For Java Project, You Can Start Building From Scratch:
1. Weather App
If you are new to development and you might have heard about APIs, it is time to start building a basic web application called “Weather App” with the help of any public API for weather data, for example, Weather API, using this API you can build features like weather forecast, historical weather data visualisation, weather alert system and more. This project will help you understand how to consume an already existing public API and level up your developer game.
2. Clock Application
Making a basic clock application is one of the beginner-friendly projects which you can start implementing by displaying a digital clock showing hours, minutes and seconds. In this project, you need to display the current time on the digital clock and you can practice CSS to enhance the UI of your project. And if you are feeling experimental then we encourage you to add features like a stopwatch, counter, and multiple timezones.
3. Rental System
The rental system is an amazing project to practice the Java object oriented programming OOP concept in your project. You can build an application like a camera rental system where you can add features like adding products, removing products, renting a camera and adding a payment gateway like Stripe, login and signup functionality, JWT Authentication and more. This application will help build a solid foundation for CRUD, User management etc.
4. Supply Chain Management Application
Supply chain management is a project where a user as a client can submit their requirements and you publish their requirements to the market and other manufacturers/ dealers can submit quotations to the clients on your platform. The client can create a list and manage all the products and raw materials which they gather from manufacturers and can manage their requirements on the application only. This project can be web-based or desktop-based.
Features of Supply Chain Management System:
- User-friendly Requirement Submission: Clients can easily submit their requirements through a user-friendly interface.
- Market Visibility: Published requirements are visible to manufacturers/dealers, enhancing market visibility.
- Quotation Management: Manufacturers/dealers can submit quotations for the client’s requirements.
- Product and Raw Material Management: Clients can create lists and manage products and raw materials gathered from manufacturers.
- Centralized Requirement Management: All requirements and interactions are managed within the application.
- Web-based or Desktop-based: The system is adaptable and can be implemented as either a web-based or desktop-based application
5. Music Player
You can create a music player using java where user can organise their music and as a feature, you can add equalizer controls so that they can edit their music by adding bass, treble etc on the music track. Additionally, you can save the tracks on the cloud and save references on the database. The goal is to be creative with the project and add aesthetics to the projects.
6. Real-Time Chatting Application
In the Java chat app, you get to explore Web Sockets, using web sockets you can establish real-time connections between endpoints so that two or more users can chat simultaneously and it gets updated in real time just like any other social media application. Try to figure out similarities with your favourite social media app and add some additional features. How about real-time code sharing and voice calling? A discord but for coders? THE SKY IS THE LIMIT.
7. Encryption And Decryption
A Java application for demonstration of different Encryption and Decryption based on symmetric and asymmetric encryption and decryption. This project will help you explore different algorithms like RSA, AES, SHA256 etc.
Try finding out how you can store passwords while signing up as a user on your application.
8. Stock Market Visualizer
Create a stock market visualization tool where you can start by using Stock Market API, and then add functionalities like filters, etc with the help of different libraries like charts js etc.
9. ChatGPT for Developers
If you are willing to spare some money on OpenAI API, You can create a developer tool using Chat GPT developer can directly enter the requirements in the terminal and using Chat GPT you can parse the response and display the command in the terminal itself.
E.g. What’s the global search command in VS Code?
This project will help you gain confidence with strings and prompt engineering with ChatGPT.
10.Resume And Portfolio Maker
A resume and a portfolio is one of the essential for the developer to showcase their skills and share them with the public but not everyone has them ready. So you can build a website where users can create their account and with their details, you can create a resume or a single-page portfolio from the templates.
In the fast-paced software development job environment it is important to build a robust portfolio whether you are a final-year student, a job seeker or a professional considering a career change. This topics for Java project play a crucial role in achieving this goal. A well-curated resume with this mini java projects can give you a head start in your interviews. In most technical interviews you are expected to explain projects and define the motive behind the projects it is very important to make those projects yourself. Along the path of project building, you gain experience in Java topics and become interview and job-ready.
There is a lot to learn about Java development, and the projects you work on can help you become an expert in the field. Now boot up your laptops, choose a project in your interest, and start building your portfolio right now. The opportunities are endless. Have fun coding!
Ans:- As a developer, the primary goal is to develop and showcase your coding skills in bug fixes, projects and solutions. If you build projects for practice you already have an edge over other developers who never practice hands-on project building.
Ans:- Selecting a project is a matter of your interest and the learning goal you set, for example, If you like touch typing and want to practice it, then you can go ahead with building a Java project where you can gamify the typing. Adding a database and leaderboard can enhance your learning in the process.
Ans:- Create a portfolio website where you document the project’s details, including its description, features, and technologies used. You can include code samples, screenshots, and links to GitHub repositories.
