# Java Training Hub
## Repository Description
🚀 Java Training Hub – A comprehensive repository containing Java exercises covering Basic Syntax, Control Flow, OOP, Data Structures, Algorithms, and Problem Solving.
This repository is designed to build a strong foundational understanding of Java, ensuring a well-rounded grasp of its core concepts. The goal is to develop backend development skills by tackling various challenges that simulate real-world scenarios.
## Topics Covered
✅ Basic Syntax & Variables – Java fundamentals, data types, and operators
✅ Control Flow – Conditional statements, loops (if/else, loops, switch-case)
✅ Functions & Recursion – Methods, recursion, and modular programming
✅ Arrays & Data Structures – Arrays, lists, stacks, queues, hashmaps, and sets
✅ Object-Oriented Programming (OOP) – Encapsulation, inheritance, polymorphism, abstraction
✅ Algorithms & Problem Solving – Sorting, searching, recursion, and logic-based challenges
## Problems Covered
### Basic Syntax Problems
* Hello World – Printing the first statement in Java
* Swap Two Numbers – Swapping two variables without a temp variable
* Even or Odd – Checking if a number is even or odd
* Find the Largest Number – Finding the largest among three numbers
* Sum of Digits – Calculating the sum of digits of a number
### Control Flow Problems
* Factorial Calculation – Calculating the factorial using loops
* Prime Number Check – Checking if a number is prime
* Reverse a Number – Reversing the digits of a number
* Fibonacci Series – Printing the Fibonacci sequence up to a limit
* Armstrong Number – Checking if a number is an Armstrong number
## Advanced Topics (Upcoming)
* Recursion & Dynamic Programming – Solving problems using recursion and memoization
* Data Structures Implementation – Implementing Linked Lists, Trees, and HashMaps
* Multi-threading & Concurrency – Understanding Java's threading model
* File Handling & Streams – Working with files and input/output streams
## Getting Started
1. Clone the repository:
```bash
git clone https://github.com/ehab-elshimi-developer/java-training-hub.git
```
2. Open the project in your preferred IDE (e.g., IntelliJ IDEA or VS Code)
3. Run the `MainController` class to execute the solutions
## Future Improvements
* Adding more advanced exercises
* Structuring solutions into modular packages for better organization
* Implementing Unit Tests to validate solutions
