Re: Can we do this with println?

In the diagram above as 'X' is any character and the remaining one is

the character to the screen in the subscript order X01, X02 and so
on.. The problem is I do not get how using "System.out.println" I can
go one line above without erasing the whole screen. Of course this is
_not_ a homework but something I am trying to do nevertheless.

In an ANSI-compliant terminal (i.e., pretty much anything other than Window's Command Prompt), the following string, when printed out, will print "XXX" at the top of the screen:

"\u001B[1;1HXXX"

(see <http://en.wikipedia.org/wiki/ANSI_escape_code> for other examples)
