Question 92
Correct Answer: B
The given code snippet uses IntStream.generate to repeatedly produce the value 1, limits the stream to 100 elements, and then sums these elements, resulting in a sum of 100. To produce the same value using a different code, we need an IntStream with 100 elements, each element contributing 1 to the sum. Among the options provided, the one that closely matches the requirement is 'IntStream.rangeClosed(1, 100).count()' as it counts the range from 1 to 100 inclusive, resulting in 100 elements. Therefore, B is the correct answer. The other options either do not produce the same number of elements or count elements incorrectly.
Discussion
[Removed]Option: B
There must be a typo in the answers since only 1 results in 100. Which is B A: System.out.println(IntStream.range(0, 99).count()); --> 99 B: System.out.println(IntStream.rangeClosed(1, 100).count()); --> 100 C: System.out.println(IntStream.range(1, 100).count()); --> 99 D: System.out.println(IntStream.rangeClosed(0, 100).map(x -> x).count()); --> 101

ONLY B is correct (D is 101 causa counting 0 to 100 boths included)
StavokOptions: BD
The code fragment generates an IntStream using the generate() method with a Supplier that always returns the value of z1, which is 1. The stream is then limited to 100 elements using the limit() method and the sum of all elements is calculated using the sum() method. The result is the sum of 100 ones, which is 100. Both statements generate an IntStream with 100 elements and then count the number of elements in the stream using the count() method. The result of both statements is 100, which is the same as the value of result.
