Error
BankBalanceLoop.java:16: cannot find symbol
symbol : variable Y
location: class BankBalanceLoop
char response = Y;

There are a few issues in your code.

You need to initialize variables newBalance & deposit

and char response = Y; should be char response = 'Y'; to get rid of this error although there are still issues here.

In future, please put the highlight tags around your code and give an actual description of your problems.
