What are some examples of custom Java interfaces?

Can you give me some examples of custom Java interfaces?

Sure! A custom Java interface is a way to define a contract for classes. For example, you might have an interface called 'Drawable' with a method 'draw()'.

What would a class implementing that interface look like?

A class like 'Circle' could implement 'Drawable' and provide the specific implementation of the 'draw()' method to render a circle.

Can you show me the code for that?

Absolutely! Here's a simple example:

interface Drawable {
    void draw();
}

class Circle implements Drawable {
    public void draw() {
        System.out.println("Drawing a circle.");
    }
}

What are the benefits of using interfaces in Java?

Using interfaces promotes loose coupling, allows for multiple inheritance, and defines a clear contract for classes.
