import java.io.PipedInputStream;
import java.io.PipedOutputStream;

public class Main extends PipedInputStream {

  public static void main(String[] args) throws Exception {

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

    PipedOutputStream out = new PipedOutputStream();
    Main in = new Main();

    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++) {
