Question

Which of these is an incorrect form of using method max() to obtain a maximum element?

(a) max(Collection c)

(b) max(Collection c, Comparator comp)

(c) max(Comparator comp)

(d) max(List c)

This question was addressed to me during an interview.

This question is from Collection Algorithms in division java.util – The Collections Framework of Java

Answer 1

The correct choice is (c) max(Comparator comp)

To explain: Its illegal to call max() only with comparator, we need to give the collection to be searched into.
