Bounded Buffers

To minimize the amount of waiting time for threads that share resources and operate at the same average speeds, we can implement a bounded buffer that provides a fixed number of buffer cells into which the Producer can place values, and from which the Consumer can retrieve those values. (In fact, we’ve already done this with the ArrayBlockingQueue class in Section 23.6.) If the Producer temporarily produces values faster than the Consumer can consume them, the Producer can write additional values into the extra buffer cells, if any are available. This capability enables the Producer to perform its task even though the Consumer is not ready to retrieve the current value being produced. Similarly, if the Consumer consumes faster ...
