(d) None of the mentioned

I had been asked this question by my college director while I was bunking the class.

My question is based upon Introduction To Methods in section Classes and Methods of Java

Answer 1

Correct choice is (b) Function overloading

Easy explanation: Function overloading is a process of defining more than one method in a class with same name differentiated by function signature i:e return type or parameters type and number. Example –  int volume(int length, int width) & int volume(int length , int width , int height) can be used to calculate volume.
