Flushes this output stream and forces any buffered output bytes to be written out.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    PipedOutputStream out = new PipedOutputStream();
    Main in = new Main();

    out.connect(in);/*from w w  w  . j av  a2 s  .  c om*/

    out.write(70);
    out.write(71);

    out.flush();

    // print what we wrote
    for (int i = 0; i < 2; i++) {
        System.out.println((char) in.read());
    }
    out.close();
}
