IntStream parallel() is a method in java.util.stream.IntStream. This method returns a parallel IntStream, i.e, it may return itself, either because the stream was already present, or because the underlying stream state was modified to be parallel.
IntStream parallel() is an intermediate operation. These operations are always lazy. Intermediate operations are invoked on a Stream instance and after they finish their processing, they give a Stream instance as output.
IntStream parallel() Where, IntStream is a sequence of primitive int-valued elements and the function returns a parallel IntStream.
Below given are some examples to understand the function in a better way.
Example 1 :
The corresponding parallel IntStream is : 9 8 11 10 6 5 7
Example 2 :
The corresponding sequential IntStream is : 5 6 7 8 9 10 11
Example 3 :
The sorted parallel IntStream is : 4 2 3 1 3 5 9
Note that it still shows as unsorted. That’s because forEach() is being used. To get the items processed in sorted order, use forEachOrdered(). But note that this negates the advantage of using parallel.
