Raining outside the Applet Window ! HELP

Question

I have set the coding for an applet 800 pixels by 800 pixels .
The Mozilla Firefox browser window cannot be modified to be that size and it is raining outside the applet !
How do I modify the RainCloud class so it only rains within
800 pixels in the x direction ?
Below is the RainCloud class and the rest
Thank you in advance
