Topic: to receive parallelStream
Is ArrayList on a small amount of elements, about equal to an amount of kernels of the processor. It is necessary to fulfill over each element that that like map and further . And to do it it is necessary parallely, operation map is fulfilled over each element of the order of 400 milliseconds. If I pull parallelStream ().map (), I receive stream, and further I do serial reduce it is clarified that Java not line. Whether it is possible as that simply to force it all the same it ? Very much it would not be desirable to write pens all these starts of flows and barriers.
