That is a good way to learn, but..

I wanted to know the keyword for clearing the screen in java in a
console program...

..note that Java is not well suited to doing 'advanced'
things with consoles. 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.

Hi Preetham,

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.

Rob

Try using:

System.out.println("\u001B[2J");

That should work in all ANSI-compliant consoles.

Thanks a lot
