                                                       ExecutionException

Similar to parallel stream but executes in ExecutorService not ForkJoinPool.commonPool(). Another difference is that execution is always forked regardless of the job size.

Parameters:

executor -

elements -

mappingFunction -

Returns:

Throws:

ExecutionException - when mappingFunction throws exception

InterruptedException
