# Java Design Patterns

This project demonstrates various design patterns in Java, including creational, structural, and behavioral patterns.

## Project Structure

```

├── main/
│   └── java/
│       ├── creatingPattern/    # Creational patterns
│       └── structuralPattern/  # Structural patterns
uml/                           # UML diagrams
└── README.md
```

## UML Diagrams

The project includes PlantUML diagrams for each design pattern. These diagrams are stored in the `uml/` directory and can be viewed using various methods:

1. Using PlantUML Online Server
2. Using VS Code Extension
3. Using PlantUML CLI
4. Using Maven Plugin

For detailed instructions on how to view and generate the diagrams, please refer to [uml/README.md](uml/README.md).

## Design Patterns

### Creational Patterns

- Singleton Pattern
- Factory Method Pattern
- Abstract Factory Pattern
- Builder Pattern
- Prototype Pattern

### Structural Patterns

- Adapter Pattern
  - Class Adapter
  - Object Adapter
  - Two-way Adapter

## Getting Started

### Prerequisites

- JDK 17 or higher
- Maven 3.6 or higher
- PlantUML (optional, for viewing UML diagrams)

### Building the Project

```bash
mvn clean install
```

### Running Examples

```bash
mvn exec:java -Dexec.mainClass="creatingPattern.singleton.HungrySingleton"
```

## Documentation
