How do I use abstract classes in Java?

Abstract classes in Java are classes that cannot be instantiated and can contain abstract methods that must be implemented by subclasses.

Can you give me an example of an abstract class?

MagicBuddy
MagicBuddy

Sure! Here's a simple example:

abstract class Animal {
    abstract void sound();
}

class Dog extends Animal {
    void sound() {
        System.out.println("Bark");
    }
}

In this example, Animal is an abstract class with an abstract method sound(), and Dog is a subclass that implements this method.

What are the benefits of using abstract classes?

MagicBuddy
MagicBuddy

Abstract classes allow you to define a common interface for all subclasses, promote code reusability, and enforce a contract for subclasses to follow.

Can I have multiple abstract methods in one abstract class?

MagicBuddy
MagicBuddy

Yes, you can have multiple abstract methods in an abstract class. Each subclass must implement all of them unless it is also declared abstract.
