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:

   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
