java-dsa-journey

A collection of Java fundamentals, problem-solving practice, and Data Structures & Algorithms implementations in Java. Documenting my learning journey step by step.

🚀 Java DSA Journey

This repository documents my journey of learning Java fundamentals and mastering Data Structures & Algorithms (DSA) in Java.
It contains code, notes, and practice problems — starting from the basics and moving towards advanced problem-solving.
