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

Usage

From source file:Main.java

public static void main(String[] args) {

    PipedWriter writer = new PipedWriter();
    PipedReader reader = new PipedReader();

    try {//  ww  w.  j a  v  a 2s.co  m
        // connect the reader and the writer
        writer.connect(reader);

        writer.write(70);
        writer.write(71);

        // flush the writer
        writer.flush();

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

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