Java pipeline stream read/write operations, used for communication between two threads

/* Java pipeline stream read/write operations are used between two threads
PipedOutputStream the PipedInputStream connection is a pipeline.
The MPs queue output stream can be written to the MPs queue. The MPs queue input stream can read data from the MPs queue.
This Decorator decoration design mode greatly enhances the java Stream Function
You can connect to the input and output streams of the pipeline when constructing a stream or connect to the stream through the connect function.
