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. Method overloading, on the other hand, allows multiple methods in the same class to have 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?

In method overloading, you might have a method add(int a, int b) and another method add(double a, double b). Both methods are named add but accept different parameter types.

Are there any performance differences between the two?

Generally, method overloading can be resolved at compile time, making it slightly faster, while method overriding is resolved at runtime, which can introduce a slight overhead.
