Typically, data is read from a <code>PipedInputStream</code> object by one thread and data is written to the corresponding <code>PipedOutputStream</code> by some other thread. Attempting to use both objects from a single thread is not recommended, as it may deadlock the thread. The piped input stream contains a buffer, decoupling read operations from write operations, within limits.<P><DL><DT><B>Since: </B><DD>JDK1.0</DD><DT><B>See Also: </B><DD><A
