thanks for the links, yes it need to redraw the whole screen (it's a
game), I wondering if it's possible to do that without any external
libs.

This may not be what the OP wants. I just downloaded it to take a look.
There is almost no documentation apart from Javadocs output from the
classes, i.e. no really explanatory overview and no example code. It
looks to me as it if its meant to be an exact analogue of the C curses
library, allowing a Java program to handle screens and forms on a
console screen rather than painting it inside an AWT or Swing window.

To the OP: from this description is this what you want or are you
looking for code that emulates a text terminal within a Swing JPanel?

If the latter, I wrote a Java glass teletype emulation that was capable
of keeping up with my typing and with data coming in on a 9600 baud
serial connection. It could handle a remote interactive login session
with no noticeable delays when run on a 300 MHz PII box. I used an 80 x
25 JTextArea to represent the screen and handled writing to it by
manipulating the text content of the JTextArea.
