Question

What is the process of defining more than one method in a class differentiated by parameters?

(a) Function overriding

(b) Function overloading

(c) Function doubling

(d) None of the mentioned

I have been asked this question during an interview for a job.

The query is from Methods Taking Parameters topic in section Classes and Methods of Java

Answer 1

Right answer is (b) Function overloading

To elaborate: 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.
