What are some examples of Java interfaces in code?

Can you explain what a Java interface is?

A Java interface is a reference type, similar to a class, that can contain only constants, method signatures, default methods, static methods, and nested types. It cannot contain instance fields or constructors.

Could you provide some examples of Java interfaces in code?

Sure! Here's a simple example:

interface Animal {
    void makeSound();
}

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

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

In this example, Animal is an interface with a method makeSound(), and both Dog and Cat implement this interface.

What are the benefits of using interfaces in Java?

Using interfaces allows for abstraction, multiple inheritance, and the ability to define a contract for classes. It promotes loose coupling and enhances code flexibility.
