Design Patterns Implementation

This project demonstrates the implementation of various design patterns in Java, organized into three main categories: Behavioral, Creational, and Structural patterns. Each pattern is implemented with practical examples and includes detailed documentation.

Project Structure

├── behavioral/     # Patterns that focus on object interaction
├── creational/     # Patterns that focus on object creation
└── structural/     # Patterns that focus on object composition

Categories Overview

Behavioral Patterns

Behavioral patterns are concerned with algorithms and the assignment of responsibilities between objects. They describe not just patterns of objects or classes but also the patterns of communication between them.

• Command Pattern
• Observer Pattern
• Iterator Pattern
• Strategy Pattern

Creational Patterns

Creational patterns abstract the instantiation process. They help make a system independent of how its objects are created, composed, and represented.

• Factory Pattern
• Builder Pattern
• Singleton Pattern

Structural Patterns

Structural patterns are concerned with how classes and objects are composed to form larger structures. They help ensure that when one part of a system changes, the entire structure doesn't need to change.

• Adapter Pattern
• Facade Pattern

Getting Started

Prerequisites

• Java Development Kit (JDK) 8 or higher
• Maven (for dependency management)
