Java OCA OCP Practice Question 2765

Question

Select from the following statements and indicate the order in which they would appear to output 10 lines:. 

Stream.generate(() -> "1") 
L:  .filter(x -> x.length() > 1) 
M:  .forEach(System.out::println) 
N:  .limit(10) 
O:  .peek(System.out::println) 
;
  • A. L, N
  • B. L, N, O
  • C. L, N, M
  • D. L, N, M, O
  • E. L, O, M
  • F. N, M
  • G. N, O


F.

Note

The terminal operation must be right before the semicolon, which is line M.

Remember that forEach() is a terminal operation while peek() is an intermediate operation.

This eliminates all but choices C, E, and F.

Choice E is incorrect because there is no limit() operation, which means that the code would run infinitely.

Choice C is incorrect because filter() is called before limit().

No elements make it through the filter, so the code also runs infinitely.

Choice F is correct.
