The class is a piped output stream that can be connected to a piped input stream to create a communications pipe.Following are the important points about PipedOutputStream −

  • The piped output stream is the sending end of the pipe.

  • Attempting to use both objects from a single thread is not recommended as it may deadlock the thread.

  • Data is written to a PipedOutputStream object by one thread and data is read from the connected PipedInputStream by some other thread.

  • The pipe is said to be broken if a thread that was reading data bytes from the connected piped input stream is no longer alive.

Class declaration

Following is the declaration for class −

public class PipedOutputStream
   extends OutputStream

Class constructors

Sr.No. Constructor & Description


This creates a piped output stream that is not yet connected to a piped input stream.


PipedOutputStream(PipedInputStream snk)

This creates a piped output stream connected to the specified piped input stream.

Class methods

Sr.No. Method & Description
1 void close()

This method closes this piped output stream and releases any system resources associated with this stream.

2 void connect(PipedInputStream snk)

This method connects this piped output stream to a receiver.

3 void flush()

This method flushes this output stream and forces any buffered output bytes to be written out.

4 void write(byte[] b, int off, int len)

This method writes len bytes from the specified byte array starting at offset off to this piped output stream.

5 void write(int b)

This method writes the specified byte to the piped output stream.
