What is the difference between method overriding and method overloading?

What is the difference between method overriding and method overloading?

Method overriding allows a subclass to provide a specific implementation of a method already defined in its superclass. In contrast, method overloading allows a class to have multiple methods with the same name but different parameters.

Can you give me an example of method overriding?

Sure! If you have a class Animal with a method makeSound(), a subclass Dog can override this method to provide a specific sound, like bark().

And what about method overloading?

For method overloading, consider a class Calculator with a method add(). You can have add(int a, int b) and add(double a, double b) as two different methods with the same name but different parameter types.

Are there any rules for overriding methods?

Yes, when overriding a method, the method in the subclass must have the same name, return type, and parameters as the method in the superclass.
