The problems I am having are when the user says True to the question "Do you want a meal plan?" The user then has to pick between 3 meal plan options. The options are meal plan stuff-your-face(4999.00), meal plan I-can't-stand-this-food(3499.00), and meal plan I'm-on-a-diet(2599.00). I'm not sure how to implement this into my student class. My main class also isn't running properly. If I put any numbers in my address I get an error. The main class also asks me to enter my phone number and to enter the credits you are taken at the same time without allowing me to answer the phone number question first. Any help and tips for my project would be greatly appreciated!

I have adjusted my student class and it works great now. My University class isn't working properly though. I get this error:
Exception in thread "main" java.lang.NullPointerException
at University.collectDataForReport(University.java:8)
