TOP ONE IS MY MAIN ONE... the second is my class...

i keep getting this error!?!?

>>

java.lang.NoSuchMethodError: main
Exception in thread "main"

any clues?.. it worked before i was showing someone how to do this...

The Method of whatever your trying to do is not correct.. try reprogramming it to use a different way to do whatever u want it to do..
I've used java before.. there's many tweaks u can do.
What exactly are you trying to do?
Looks like some sort of "internet quiz".

java is for cheese mechanics.
