How do I implement inheritance in Java?

Inheritance in Java allows a class to inherit properties and methods from another class. You can implement it using the 'extends' keyword.

Can you give me an example of inheritance?

Sure! If you have a class 'Animal' and a subclass 'Dog', you can write:

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

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

Here, 'Dog' inherits the 'eat' method from 'Animal'.

What if I want to override a method?

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."); } }

This will change the behavior of the 'eat' method for the 'Dog' class.

Are there any limitations to inheritance in Java?

Yes, Java does not support multiple inheritance with classes to avoid ambiguity. However, you can achieve multiple inheritance through interfaces.
