DoubleStream forEach(DoubleConsumer action) performs an action for each element of the stream. It is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect.
void forEach(DoubleConsumer action)
- DoubleConsumer : Represents an operation that accepts a single double-valued argument and returns no result. This is the primitive type specialization of Consumer for double.
Note : The behaviour 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 :
7.3 8.2 9.5 10.6
Note : For parallel stream, DoubleStream forEach(DoubleConsumer 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 2 :
9.5 7.3 8.2 10.6
