Im getting this NullPointerException which seem to be pointing to whenever i check the variables newUser, newPass, checkUser, checkPass. I did some research on java docs and StackOverflow and saw that its because the values are not being initialized with a value, therefore are null. I decided to initialize it with = "";. This fixed my null Exception issue however it seems as though the values are not updating from .getText() and are seen as "Empty". Im not sure how to fix this now.
