Description




Is there such a command as a "cls" (clear screen), like in DOS or basic, that can be used in a java application (not applet)? If not, is 
there something similar, other than using a bunch of System.out.println statements? I'm using MS Visual J++ 
(and not impressed with it).
This is for a programming assignment that uses menus in the stand-alone interpreter. 
                                     Thanks.

Work Around
N/A
Evaluation
Java currently has no support for clearing the console window (in Unix parlance,
the tty).  There has, as yet, been hardly any demand for this feature or for
other termcap-style features.  --   xxxxx@xxxxx   3/5/1998

There still has been hardly any demand for this feature.  We are considering an
API for improved interactive console I/O (see 4050435), but we see no need to
replicate termcap in Java.  --   xxxxx@xxxxx   2002/3/15

Partial workaround: you may write (vt100) control sequences directly to System.out, such as ESC 2 J or ESC [ K or ... (search the web for xterm control sequences).  However, I know no way of turning out line echoing or line buffering, (stty -echo -icanon).
