Classes to support functional-style operations on streams of elements, such as map-reduce transformations on collections. For example: int sum = widgets.stream() .filter(b -> b.getColor() == RED) .mapToInt(b -> b.getWeight()) .sum(); ...
A stream should be operated on (invoking an intermediate or terminal stream operation) only once. This rules out, for example, "forked" streams, where the same source feeds two or more pipelines, or multiple traversals of the same stream. A stream implementation may throwIllegalStateExceptionif ...
