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 means Dog will have all the characteristics of Animal.

Can you give me a code example of that?

Sure! Here's a simple example:

class Animal {
    void eat() {
        System.out.println("This animal eats food.");
    }
}

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

public class Main {
    public static void main(String[] args) {
        Dog myDog = new Dog();
        myDog.eat(); // Inherited method
        myDog.bark(); // Dog's own method
    }
}

What if I want to override a method in the subclass?

You can override a method in the subclass by defining a method with the same name and parameters. For example:

class Dog extends Animal {
    @Override
    void eat() {
        System.out.println("The dog eats dog food.");
    }
}

That's really helpful! What are some other concepts related to inheritance?

Other concepts related to inheritance include polymorphism, encapsulation, and interfaces. Polymorphism allows methods to do different things based on the object that it is acting upon.
