This repo covers Java fundamentals, OOP, DSA, Multithreading, Concurrency, Java 8 features, Exception and file Handling, and the Collections Framework. It also includes real-world projects, and coding challenges from platforms like LeetCode and HackerRank to strengthen problem-solving and Java skills.
| Project Name | Description | Key Features | Technology Used | Concepts Covered |
|---|---|---|---|---|
| Console Based Tic-Tac-Toe Game | A Console-based Tic-Tac-Toe game in Java is a simple command-line application where two players take turns to mark 'X' or 'O' on a 3x3 grid. The game checks for winning conditions after each move. The program handles player input, displays the updated board after each turn, and announces the winner or a draw when the game concludes. | A Console-Based Tic-Tac-Toe game in Java allows two players to take turns marking 'X' or 'O' on a 3x3 grid, with win, draw, and input validation features. The game continuously updates the board and announces the result after each move. | Core Java | Arrays, Control Flow Statements (Loops, Conditionals), Methods, String Manipulation, User Input, Game Logic |
| Library Management System | A Java-based Library Management System using CRUD operations, OOP principles, and exception handling to efficiently manage books via a console interface.
