Interfaces in Java

 Interfaces in Java

Interfaces define a set of methods that a class must implement. This allows you to create code that is more flexible and modular.

Example code:

csharp

public interface Drawable {

    void draw();

}

public class Circle implements Drawable {

    public void draw() {

        System.out.println("Drawing a circle.");

    }

}

Circle myCircle = new Circle();

myCircle.draw(); // prints "Drawing a circle."
