Update system.out

Question

Hi,
I was just wondering if it was possible to instead of printing a new line of data using System.out.println() you could instead update the current line to something else.
Just that I will be printing something out every second and don't want 60 lines after a minute has gone by.
Thanks

public class Printing {
    public static void main(String[] args) {
        System.out.print("\rABCD");
        System.out.println();
        System.out.print("\rEFGH");
        System.out.println();
        System.out.print("\r1234");
        System.out.print("\r5678");
        System.out.println();
}This is the output:
ABCDEFGH
12345678>
This is what I would like the output to be.
5678Although I am running Java 1.6.0 on a windows Vista machine so that may be the reason why it wont work.

If so, you need a third-party curses library such as JCurses. Sourceforge.net is a good place to start, search for java curses librariesYes that is correct and I will look into your suggestion and compare them to my other ideas.
Thanks again
