Software Design Patterns

 Software Design Patterns

Software design patterns are reusable solutions to common software design problems. They help improve the flexibility, maintainability, and scalability of software.

Example of the Singleton pattern in Java:

public class Singleton {

  private static Singleton instance;

  private Singleton() {}

  public static Singleton getInstance() {

    if (instance == null) {

      instance = new Singleton();

    }

    return instance;

  }

}
