void forEach(IntConsumer action)
Parameter : IntConsumer represents an operation that accepts a single int-valued argument and returns no result. This is the primitive type specialization of Consumer for int.
Note : The behavior of this operation is explicitly nondeterministic. Also, for any given element, the action may be performed at whatever time and in whatever thread the library chooses.
Example 1 :
7 8 9 10
Example 2 :
4 5 6 7 8
Note : For parallel stream, IntStream forEach(IntConsumer action) does not guarantee to respect the encounter order of the stream, as doing so would sacrifice the benefit of parallelism. Below is the example.
Example 3 :
6 8 7 5 4
