Depending on the class you're doing this for, you may consider making this application more object oriented. One of the classes I took early on in CS was OOP with java, and we'd get extra points if we used some of the concepts from the lectures. This source reads more like a c source file than a java one, not that this is a bad thing if you're still learning.
If it doesn't matter, then it may be over kill, but a simple change would be creating a Quiz class that contains all the quiz related logic and handles creation of question and answer classes (or strings whatever you choose). The advantage of using OOP design is data encapsulation and modularity.
Just my 2 cents
