☕ Java DSA & Core Concepts Practice

Welcome to my Java practice repository! This space is dedicated to my journey of learning and mastering Data Structures and Algorithms (DSA), Object-Oriented Programming (OOP), and the fundamentals of the Java programming language.

📂 Repository Structure

The code is organized into directories based on the concepts being practiced.

Data Structures & Algorithms (DSA)

• Arrays: Basic operations, searching, sorting
• Linked Lists: Singly linked list implementations
• Stacks: Implementation using arrays and linked lists
• Queues: Queue implementations and operations
• Trees: Binary tree operations
• Searching Algorithms: Various search implementations
• Sorting Algorithms: Bubble Sort, Selection Sort, Insertion Sort, Merge Sort, Quick Sort
• Recursion: Basic and advanced recursion problems
• Backtracking: Permutation and path finding algorithms
• Hashing: HashMap and HashSet implementations

Note: Checked items are completed, unchecked are in progress or planned.

🚀 How to Run the Code

1. Clone the repository:

   git clone https://github.com/singh-odyssey/java.git
   cd java

2. Compile a Java file:

   javac directory/FileName.java

   For example:

   javac sorting/BubbleSort.java

3. Run the compiled code:

   java directory.FileName

   For example:

   java sorting.BubbleSort
