import java.io.*;

public class PipedOutputStreamDemo extends PipedInputStream {

   public static void main(String[] args) {

      byte[] b = {'h', 'e', 'l', 'l', 'o'};

      // create a new Piped input and Output Stream
      PipedOutputStream out = new PipedOutputStream();
      PipedInputStreamDemo in = new PipedInputStreamDemo();

      try {
         // connect input and output
         out.connect(in);

         // write something 
         out.write(b, 0, 3);

         // flush the stream
         out.flush();

         // print what we wrote
         for (int i = 0; i < 3; i++) {
            System.out.print("" + (char) in.read());
         }


      } catch (IOException ex) {
         ex.printStackTrace();
