No idea what you mean. It compiled fine.

That response makes it sound like you are entirely unfamiliar with the possibility that you might have errors at run-time. That being the case, you should stick to writing ordinary applications until you get a bit more experience with the language. Applets are not a technology for beginners.

It's homework.

paint( g, ranNum, card );

does something look strange here?

I had no idea what to set it too so I out null there as a temp.

I am writing an applet that randomly selects 10 cards and then displays them. I can compile my code fine but when I run it, the applet viewer says Start: Applet not initialized. I am unsure what is wrong with my code, can anyone help?
