While I play with applets, I like to place output strings throughout the
code, just to make sure the applet reaches certain critical points.
However, I'm never sure what the applet does as none of the debugging
strings I use in the program ever show up (or rarely show up) -- I think
it's a combination of threading and repainting. So I started using sounds at
certain places in the program to see if execution reached that point. Even
though this works ok, I'd much rather see string messages displayed in a
window. What I should do before playing around with too many more applets is
find a way of displaying output on the screen while the program runs, no
matter what, so I can easily trace the program execution. Otherwise I never
know if an applet ends or aborts. I tried using showStatus(), but the status
line information rarely stays for long, if I see it flash by at all.
I'm writing Beta applets and using Netscape to view them, but I don't think
any of the System.out (or whatever the commands are for standard output)
work at all. When I try to put strings into the repaint method, I have
strings repainted over top of strings fast enough that this method is rather
useless. I thought that I might be able to write information to a file, but
is there an easier method, like the debugger -- I still haven't got that
thing to run yet (I haven't downloaded the new JDK 2.0 w/interactive
debugger yet either). I'm looking for a clean, slick, and rather painless
way of doing this. Any suggestions?
