It is probably better to concentrate on learning the core Java classes, and anytime you feel it is appropriate to clear the console, do a loop of System.out.println(""); to print a number of blank lines. -- Andrew Thompson http://www.athompson.info/andrew/ Message posted via JavaKB.com http://www.javakb.com/Uwe/Forums.aspx/java-general/200705/1 Back to top Robert Mark Bram Guest Posted: Wed May 16, 2007 7:12 am    Post subject: Re: Basic Question Hi Preetham, Quote: I wanted to know the keyword for clearing the screen in java in a console program... There is no keyword or command for doing this, because Java doesn't actually write to a console as such - it writes to an 'output stream', with no understanding of whether that output stream is being displayed on a console.. never mind what sort of console (dos, xterm etc). Instead, what you could do is write enough empty lines to clear your console: for (int index = 0; index < 80; index++) { System.out.println(""); } The biggest problem with this is how many times should you do it? If you say "80", you should somehow make sure that all the other people who are going to run your app have consoles that display 80 lines or less. Hope this helps.

Try using: System.out.println("\u001B[2J"); That should work in all ANSI-compliant consoles.
