RE: a few java questions

["Paul Robson" <probson@powerup.com.au>]

try this:

javac uitest.java -Xstdout > error.txt

it works.  I guess javac defaults to outputting to stderr (which just
happens to be the console) instead of stdout, and stderr doesn't get
redirected for some reason.


and for the rest of the code... you are using the old event model for one
thing (i tried not to change too much of that.. had to delete some things)
and also i couldn't get it to work using applet.  seeing as you obviously
want an application... i just used Frame.  I'll leave it to you to figure
out which bits have changed.
