What is the difference between overriding and overloading?

Can you explain the difference between method overriding and method overloading?

Sure! Method overriding occurs when a subclass provides a specific implementation of a method that is 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?

Absolutely! If you have a class called Animal with a method makeSound(), and a subclass Dog overrides this method to return 'Bark', that's method overriding.

What about method overloading? Can you show me that?

Sure! In a class Calculator, you might have a method add(int a, int b) and another method add(double a, double b). Both methods are named add, but they take different parameter types, which is method overloading.

Are there any performance differences between the two?

Generally, method overriding can be slightly slower due to dynamic method dispatch, while method overloading is resolved at compile time, making it faster. However, the difference is usually negligible.
