DoubleStream parallel() in Java
DoubleStream parallel() is a method in java.util.stream.DoubleStream. This method returns a parallel DoubleStream, i.e, it may return itself, either because the stream was already present, or because the underlying stream state was modified to be parallel.
DoubleStream 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.
DoubleStream parallel() Where, DoubleStream is a sequence of primitive double-valued elements and the function returns a parallel DoubleStream.
Example 1 :
The corresponding parallel DoubleStream is : 4.5 7.8 12.6 5.2
Example 2 :
The corresponding sequential DoubleStream is : 5.2 12.6 4.5 7.8
Example 3 :
The sorted parallel DoubleStream is : 4.5 6.6 2.3 3.0
