In addition to method parallelSort, class Arrays now contains methods parallelSetAll and parallelPrefix, which perform the following tasks:

• parallelSetAll—Fills an array with values produced by a generator function that receives an int and returns a value of type int, long or double. Depending on which overload of method parallelSetAll is used, the generator function is an object of a class that implements IntToDoubleFunction (for double arrays), IntUnaryOperator (for int arrays), IntToLongFunction (for long arrays) or IntFunction (for arrays of any non-primitive type).

• parallelPrefix—Applies a BinaryOperator to the current and previous array elements and stores the result in the current element. For example, ...
