"A sequence of Stream operations (called a pipeline) allows you to pass only one result from each step on to the next stage of the pipeline. If you want to pass multiple results, you must pass them as an object, but creating an object for the result of each individual comparison would hurt the performance of a stream approach compared to chunked approaches. Streams let's you handle this case efficiently by alowing you to pass a mutable intermediate container object which gets executed for each element. "
