How do I implement interfaces in Java?

To implement an interface in Java, you use the 'implements' keyword in your class definition. Would you like an example?

Yes, please provide an example.

Sure! Here's a simple example:

interface Animal {
    void makeSound();
}

class Dog implements Animal {
    public void makeSound() {
        System.out.println("Woof!");
    }
}

This defines an interface Animal and a class Dog that implements it.

What if I want to implement multiple interfaces?

You can implement multiple interfaces by separating them with commas in the class definition. For example:

class Cat implements Animal, Pet {
    public void makeSound() {
        System.out.println("Meow!");
    }
}
