Streams in Memory

In the last several chapters, you've learned how to use streams to move data between a running Java program and external sources and data stores. Streams can also be used to move data from one part of a Java program to another. This chapter explores three such classes. Sequence input streams chain several input streams together so that they appear as a single stream. Byte array streams allow output to be stored in byte arrays and input to be read from byte arrays. Finally, piped input and output streams allow output from one thread to become input for another thread.
