What are some examples of inheritance in Java?

Inheritance in Java allows a class to inherit properties and methods from another class. For example, if you have a class Animal, you can create a subclass Dog that inherits from Animal. This way, Dog can use methods defined in Animal.

Can you give me a code example of that?

Sure! Here's a simple example:

class Animal {
    void sound() {
        System.out.println("Animal makes a sound");
    }
}

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

public class Main {
    public static void main(String[] args) {
        Dog dog = new Dog();
        dog.sound(); // Output: Dog barks
    }
}

What is the benefit of using inheritance?

Inheritance promotes code reusability and establishes a natural hierarchy between classes, making it easier to manage and extend code.

Are there any drawbacks to using inheritance?

Yes, excessive use of inheritance can lead to a complex hierarchy and make the code harder to understand. It's important to use it judiciously.
