Singleton Design Pattern Demo

Overview

This project demonstrates the Singleton Design Pattern, a creational design pattern that ensures a class has only one instance and provides a global point of access to it.

What is Singleton?

• Ensures only one instance of a class exists.
• Provides a global access point to that instance.
• Useful for managing shared resources like database connections, configuration settings, or logging.

Why Use Singleton?

• Controls access to shared resources.
• Saves memory by avoiding multiple instances.
• Maintains consistent state across the application.

How It Works

• The class constructor is made private or restricted.
• A static method (e.g., getInstance()) returns the single instance.
• The instance is created on first use (lazy initialization).
