okay, i've got a program for my java class that i'm having a little trouble
with. the user input their birthday ( 2 digit mos, 2 digit day, 2 digit
year) and there are 3 JButtons, calculate, clear and exit. the clear and
exit are fairly simple, but i'm having trouble with the calculate button.
the logic for the calc button is fairly straight forward, but the problem
i'm having is getting the JTextField inputs into the calculations. how do
i take the text inputs and make them integers so i can use them to run the
needed calculations?

hope this makes sense to everybody, thanks for any help that anybody can
give.
