Java OCA OCP Practice Question 1717

Question

Which fills in the blank so the code is guaranteed to print 1? 

Stream<Integer> stream = Stream.of(1, 2, 3);
System.out.println(stream.___);
  • A. findAny()
  • B. first()
  • C. min()
  • D. None of the above


D.

Note

Option A is incorrect because the findAny() might not return 1.

The result could be any of the three numbers.

Option B is incorrect because there is no first() method available as a terminal operation.

Option C is tempting because there is a min() method.

However, since we are working with a Stream, this method requires a Comparator as a parameter.

Therefore, Option D is the answer.
