Design Patterns Samples

This repository contains sample source code implementations of various design patterns.
The purpose is to provide a clean and practical reference for developers who want to understand how design patterns can be applied in real projects.

All examples are organized by categories → design patterns → programming languages.

🚀 Usage

1. Navigate to the pattern folder you want to study.
2. Choose the programming language (e.g., Java, Php).
3. Open the source code files.
4. Compile and run them locally.

Examples:

Java:

# Structure demo (basic implementations)
cd Creational/Singleton/Java/Structure
javac *.java
java Main

# Example demo (real-world example)
cd ../Example
javac ../Structure/*.java *.java
java Main

PHP:

# Structure demo (basic implementations)
cd Creational/Singleton/Php/Structure
php Main.php

# Example demo (real-world example)
cd ../Example
php Main.php
