Method Overloading and Overriding

Question 1

What is the other name for method overloading?

Static Polymorphism

Question 2

How can you implement method overloading?

Answer 2

Implemented by having multiple methods with the same name in a class but with different arguments. Methods can have different number of parameters, different data type of parameters, different sequence of data type of parameters.

Question 3

Why can’t the return type be different with method overloading?

Answer 3

This will lead to ambiguous behaviour.

Question 4

How do we implement method overriding?

Answer 4

To override a method, we just provide a different implementation of a method with the same name in the subclass.

Question 5

Are we allowed to override a static method in java?

Answer 5

Java does not allow overriding a static method. If you create a static method with the same name in a subclass, then it is a new method.
