About the Repository

This repository is intended for students, beginners, and professionals who want to learn Java step by step and develop strong programming and problem-solving skills.
The folders are organized in a logical learning order — starting from basic Java syntax to advanced DSA patterns and interview-focused problem sets.

---

Topics Covered

• Java Fundamentals (syntax, variables, data types, control flow, operators, methods)
• Object-Oriented Programming (classes, objects, inheritance, polymorphism, abstraction, encapsulation)
• Collections Framework (List, Set, Map, Queue)
• Exception Handling
• Advanced Java (generics, streams, lambdas, multithreading)
• SOLID Principles & Other Design Principles
• Data Structures (arrays, linked lists, stacks, queues, trees, graphs)
• Algorithms (sorting, searching, dynamic programming, greedy techniques)
• LeetCode & competitive programming problems
• DSA problem-solving patterns

---

Getting Started

Prerequisites

• Java JDK 8 or above
• IDE such as IntelliJ IDEA / Eclipse / VS Code
• Git (optional but recommended)

Clone the Repository

git clone https://github.com/N-MohammedShakeel/Java_Bootcamp.git

How to Use This Repository

• Beginners should start with JavaBasics and OOPs
• Move to Collections and Advanced_Java for intermediate mastery
• Use the SOLID_Principle and Other_DesignPrinciples folders to understand clean architecture
• For interview preparation, move to DSA, DSA_Patterns, and Leetcode
• Modify and run programs for better understanding — hands-on learning is highly encouraged
