This PR transforms the repository from a basic placeholder into a comprehensive Java learning resource that addresses the goal "Time to practice from Simple to Complex".
What's Been Added
📁 Structured Learning Path
The repository now features a three-tier difficulty progression:
🎯 Complete Program Collection
Simple Level Programs:
HelloWorld.java- Introduction to Java syntax and outputVariables.java- Data types and variable declarations with examplesBasicCalculator.java- Interactive calculator demonstrating user input and arithmeticConditionalStatements.java- Grade calculator using if-else logicLoops.java- Comprehensive loop examples (for, while, do-while, nested)Medium Level Programs:
Student.java- Complete OOP demonstration with encapsulation, constructors, and methodsArraysAndCollections.java- Arrays and ArrayList operations with real-world examplesFileHandling.java- File I/O operations with proper exception handlingComplex Level Programs:
MultithreadingExample.java- Producer-consumer pattern with thread synchronizationDesignPatterns.java- Implementation of Singleton and Factory design patternsAdvancedAlgorithms.java- QuickSort, MergeSort, Binary Search, Fibonacci, and Tower of Hanoi📚 Enhanced Documentation
🛠️ Developer Experience Improvements
.gitignoreto exclude build artifactsEducational Impact
This implementation provides a complete learning journey for Java developers:
Each program includes detailed comments explaining the concepts being demonstrated, making it an excellent reference for self-study or classroom use.
