the error show in line 96 public static void main
the error is llegal static declaration in inner class Question1.Question1Listener

Looks like you messed up your brackets.
At line 66 you are still in the QuestionListener inner class, wheras I expect you inetnded to close that class definition first and have main as a method of the Question1 class.

ps: Always use your IDE's formatting to indent your code correctly. That's the quickest way to see errors lik ethis.

pps I tagged this Java for you - always tag with the language so the right people read it.
