16. What do you mean by stream pipelining in Java 8?

Stream Pipelining is done by dividing the operations which can happen on the flow into two categories. The first is Intermediate operations and the SECOND is TERMINAL operations. The common operations return the stream itself so that the result can be pipelined. The terminal operations remain at the END of the pipelining operation. It returns the final value, and the pipeline is terminated.
