Welcome to a comprehensive Java learning repository designed for juniors and beginners who want to master Java without learning 100 new things at once. This hub provides a structured pathway from basics to advanced topics like Spring Boot, DSA, and AI/Agents with Java.

• Variables, Data Types, Operators
• Control Flow (if-else, loops, switch)
• Methods & Functions
• Arrays & Collections (List, Map, Set)
• Exception Handling

• Classes & Objects
• Inheritance, Polymorphism
• Encapsulation & Abstraction
• Access Modifiers
• Interfaces & Abstract Classes
• Static & Inner Classes

• Trees (Binary, BST, Balanced Trees)
• Graphs & Graph Algorithms
• Sorting & Searching Algorithms
• Dynamic Programming
• Each topic includes LeetCode links for practice

• Spring Boot Fundamentals
• REST APIs
• Database Integration (JPA, Hibernate)
• Application Structure
• Best Practices

• Introduction to AI in Java
• LangChain4j Guide (RAG, Agents, Tools)
• Agentscope Tutorial
• Multi-Agent Architectures
• Practical Examples (Document Retrieval, Code Generation)

1. Start with Java Basics - Master fundamentals first
2. Move to OOP - Build strong OOP concepts
3. Practice DSA - Enhance problem-solving skills
4. Explore Java Backend - Build real applications
5. Dive into Master AI - Learn cutting-edge AI integration

1. See CONTRIBUTING.md for guidelines
2. Add new lessons, examples, or DSA problems
3. Update LeetCode links and difficulty tags
