Totals not printing correctly and displaying zeros in java program

Totals not printing correctly and displaying zeros in java program

Hi everyone I have almost finished this program except that my totals are
not displaying their correct values they are only displaying zeros. I've
looked through for ages and find why this is happening. Can someone please
help me here? The totals are calculated in the getTotals() method near the
bottom. Thanks!
