Java DSA (Data Structures & Algorithms) 📘

Welcome to Java DSA, a hands-on learning repository where I practice and explore core Java programming concepts, basic data structures, and algorithm exercises. This project focuses on building a strong foundation in Java before moving on to advanced DSA topics.

📍 Overview

This repository is created for beginners who want to:

  • Learn Java programming fundamentals
  • Practice logic building with loops, arrays, and methods
  • Understand 1D and 2D array operations
  • Prepare for data structures and algorithms interviews
