Console Menu

[David Serio]

Hello, I am trying to create a console application. I can present the user with a menu, read the choice, do "something" and return to the menu. However, I would rather clear the screen when showing the menu again. Something like "cls". I am using the command line in Windows XP (Start --> Run --> cmd). Currently the output all runs together, unless I put a bunch of println statements in the code, which doesn't look to nice.

I tried putting this line before outputting the menu, but Java didn't like it when I ran the app:

java.lang.Runtime.getRuntime().exec("cls");

With this line Java didn't complain, but didn't clear the screen either...

java.lang.Runtime.getRuntime().exec("cmd /c cls");


Any pointers?

Thanks,
David

And never go anywhere near Runtime.getRuntime().exec(); until you have read Michael Daconta when Runtime.exec() won't.

Thanks all for the info. I may just use a JTextArea and use that as my "console".
