Stream forEachOrdered() method in Java with examples
Stream forEachOrdered(Consumer action) performs an action for each element of this stream, in the encounter order of the stream if the stream has a defined encounter order. Stream forEachOrdered(Consumer action) is a terminal operation i.e, it may traverse the stream to produce a result or a side-effect.
void forEachOrdered(Consumer<? super T> action) Where, Consumer is a functional interface which is expected to operate via side-effects. and T is the type of stream elements.
Note : This operation processes the elements one at a time, in encounter order if one exists. Performing the action for one element happens-before performing the action for subsequent elements.
