# JavaPlayground

A collection of **Java backend practice projects** and **coding exercises** created to explore and refine skills in:

- Core Object-Oriented Programming (OOP) concepts

- Data structures and algorithms

- Backend development patterns and principles

This repository is part of an ongoing **Java skill development** and **portfolio-building** process, with a focus on preparing for backend engineering roles.

---

## 📂 Structure

### **1. Core Java & OOP**

Examples and mini-projects covering:

- Classes & Objects

- Inheritance & Interfaces

- Encapsulation & Abstraction

- Polymorphism

### **2. Problem-Solving**

Algorithmic challenges and solutions (primarily from LeetCode):

- Arrays & Strings

- HashMaps & Sets

- Recursion & Dynamic Programming

- Sorting & Searching

### **3. Backend Practice**

Small backend-oriented projects simulating real-world concepts:

- User and game management systems

- Data persistence mockups

- System design patterns

---

## 🛠️ Tech Stack

- **Java 17 (Eclipse Adoptium)**

- **IntelliJ IDEA** for development

- **Git & GitHub** for version control

---

## 📌 Goals

- Strengthen Java fundamentals for production-level backend development

- Build a consistent problem-solving portfolio

- Prepare for technical interviews in backend engineering roles

---

## 🚀 How to Run

1. Clone the repository:

   ```bash

   git clone https://github.com//JavaPlayground.git

2. Open in IntelliJ IDEA

3. Select the **Java 17 SDK**

4. Run the desired class with `main()` method
