Hello all,

i habe wrote a code piece like the following:

import java.io.*;

public class PrintWriterDemo
{
    public static void main(String[] args) throws IOException
    {
 PrintWriter pw = new PrintWriter(System.out, false);
 pw.println("this is a String.");

 int i=-7;
 pw.println(i);

 double d = 2.4e-7;
 pw.println(d);
    }
}

when i run this programm, it output nothing, until i changed the parameter
of the constructor of PrintWriter from "false" to "true". I know that the
boolean paremeter means that "autoFlush - A boolean; if true, the println()
methods will flush the output buffer". But i cann't good understand it. Can
anyone explain it to me?

Thanks a lot!

Zhilei
