You'll need to call some system specific code.
Google java+clrscr.

Use JNI to call clrscr.

Or use exex to call an external CLR command.

Google java+clrscr.

or java+curses

And after all that googling simply - don't do it.
Use a proper GUI - it may even look and feel like a text terminal.

And that is good advice!

One way is to use the Jansi library ( http://jansi.fusesource.org/ ).

There is no similar method in Java. Windows has a command "cls" that
causes the DOS window to be cleared. It is an internal command specific
to Windows. Linux has a "clear" command which scrolls the window up to
clear it.

You could duplicate the Linux style clear command easily enough,
although I don't know of any way to determine how many lines the window
has. It may be possible to use Runtime.exec to issue these commands but
I've never been able to get it to work.

You should take a look at the Console class if you are going to do a
terminal based program.

Pressing ctrl+l from keyboard clears the Linux console. Maybe
System.out.print(CTRL_L); will do it? I did not test..

Very unlikely.

Typical there is a big difference between input and output.

It is 25 years since I have last seen a half duplex terminal.

I haven't thought about one in at least that long .
