Tools & Frameworks: Spring Boot, MongoDB, WebSocket for real-time updates, and Thymeleaf or Angular for front-end.

A social media platform demonstrates your expertise in building scalable, user-driven applications. You can also showcase your front-end skills by building a sleek, user-friendly interface for the platform.

8. Weather App Using APIs

A weather app that pulls real-time weather data using third-party APIs is a great way to demonstrate your API integration skills. This type of project involves making requests to external APIs, processing the data, and displaying it in a user-friendly manner.

Key Concepts: API integration, JSON parsing, and UI/UX design.
Tools & Frameworks: JavaFX for the user interface, OpenWeatherMap API for data, and GSON for JSON parsing.

This project showcases your ability to work with external APIs and handle dynamic, real-time data—a valuable skill in today’s API-driven development environment.

9. Task Management App

A task management app helps users create, edit, and manage tasks or projects. This project demonstrates your ability to build a user-friendly and functional tool for productivity.

Key Concepts: Task creation, user management, and notifications.
Tools & Frameworks: Spring Boot, Hibernate, and JavaFX or Angular for the front-end.

This project shows that you can build productivity-focused tools, manage user input, and design intuitive user interfaces.

10. Game Development with JavaFX

Developing a simple 2D game using JavaFX allows you to show off your skills in GUI programming, game logic, and animations. Although Java isn’t commonly used for game development in the industry, it’s a great way to demonstrate your programming creativity and problem-solving skills.
