What are some examples of method overriding in Java?

Method overriding in Java allows a subclass to provide a specific implementation of a method that is already defined in its superclass. For example, if you have a class Animal with a method makeSound(), a subclass Dog can override this method to provide a specific sound like 'Bark'. Would you like to see more examples?

Yes, please provide another example.

Sure! Consider a class Shape with a method draw(). The subclass Circle can override the draw() method to implement how a circle is drawn. This allows for polymorphism, where the method that gets called is determined at runtime based on the object type.

Can you explain why method overriding is useful?

Method overriding is useful because it allows for dynamic method dispatch, enabling polymorphism. This means that the correct method is called based on the object type at runtime, which enhances flexibility and reusability in code.

What are the rules for method overriding?

Some key rules for method overriding include: the method in the subclass must have the same name, return type, and parameters as in the superclass, and it cannot be more restrictive than the original method.
