Java code to clear screen?

Anyone know any simple code that can clear the screen at a certain stage, all i could think to do was setup a loop with a load of System.out.println(""); statements which would loop until the screen was clear?

Depends on the OS... on Windows 9x and Unix, you can use:

System.out.println(((char) 27)+"[2J"); // ANSI clear screen...

But NOTHING works in Windows NT. So you can use your method above for NT as that's the best bet.

Hope this helps!

Ye figured that much, asked my programming lecturer and she didnt even have an answer, will have to stick with the ol loop.

how about this

String clearScreenCommand = null;
if( System.getProperty( "os.name" ).startsWith( "Window" ) )
   clearScreenCommand = "cls";
else
   clearScreenCommand = "clear";

Runtime.getRuntime().exec( clearScreenCommand );

checks if it's running windows and all
