📘 Java Data Structures Course – Round 2

Welcome to the official repository for the Java Data Structures Course – Round 2 🎉.
This course is another hands-on journey into data structures with Java, starting from zero with fresh explanations, examples, and exercises.

Whether you’re just beginning your path or looking for a clean restart, this round is built to give you solid foundations step by step.

🧠 What You’ll Learn

  • 📦 ArrayList – dynamic arrays and internal logic
  • 🔗 LinkedList – singly and doubly linked lists
  • 🧱 Stack – LIFO behavior with use cases
  • 📬 Queue – FIFO, circular queues, and variations
  • 🧮 Recursion – single, double, and backtracking
  • 🗃️ HashMap & HashSet – map fundamentals
  • 🌲 Trees – binary trees, traversals, and BSTs
  • 🕸️ Graphs – adjacency list, BFS, DFS, and basic pathfinding
  • 🧩 Problem Solving – multiple coding problems for each structure

🔧 Each data structure includes:

  • A full Java implementation from scratch
  • A main class for quick testing
  • A Problems class for practice
