Java Learning Repository

This repository contains a collection of Java projects created for learning and practice purposes. It covers a wide range of topics, from fundamental programming concepts to small, interactive games. Each project is self-contained in its own directory, making it easy to explore and understand individual topics.

Directory Structure

The repository is organized into a series of directories, each representing a specific Java concept or a mini-project. Every project directory includes:

• A src folder containing the Java source code.
• An .iml file, which is the project file for IntelliJ IDEA.

This structure allows you to open each directory as a separate project in your IDE.

Topics Covered

The projects are divided into two main categories:
