Create a simple calendar that displays the current date and allows users to navigate through months and years. Great for practicing Java Swing components.
Build a basic text editor that supports writing, saving, and opening .txt files—just like Windows Notepad. Ideal for learning file handling and GUI design.
Develop an app that converts one currency to another using static or live exchange rates. A good exercise in arithmetic operations and user input.
Let the user guess a randomly generated number. Display hints like “Too High” or “Too Low”. Perfect for beginners learning control flow.
Design a tool that converts units like kilometers to miles or Celsius to Fahrenheit. A beginner-friendly project to practice GUI and mathematical logic.
Create a basic authentication system with username and password verification. Store credentials in files or simple databases.
Build a CRUD (Create, Read, Update, Delete) app that stores student records such as name, roll number, and marks. Practice file handling or JDBC here.
Encrypt and decrypt text files using basic algorithms like Caesar Cipher. A good introduction to file I/O and basic cryptography.
Simulate banking operations like deposit, withdrawal, and balance inquiry. Store data in files or databases and apply basic validation rules.
Create a calculator that includes advanced functions like sine, cosine, logarithms, and exponents. Use Java Swing or JavaFX for GUI.
