After searching for a way of clearing the terminal (or console, as you prefer), I found this post «Language Agnostic Clearing of Console Screen: Without clear() or cls()«. It’s a pretty good option, easy and without complicated tricks to do this.
On Java:
public class ansiclrscr {
public static void main(String[] argv) {
System.out.print("foo\nbar\nbaz\nquux");
System.out.print("33[2J33[;H");
System.out.print( "I am at cursor position 0,0 on a clean screen.");
}
}
Simple, isn't it?
