A bit of problem here, if anyone can help, I would appreciate any and all help with this. Thank you in advance.
Now I have no errors but when I execute the program I get this:
Big Bank: Monthly Checking Account Activity
----------- Account ----------- Beginning With- Ending Over- Credit Cd
Name Id Type Balance + Deposit - drawal - Fee = Balance draft Advance
Exception in thread "main" java.lang.NullPointerException
at CheckingAccountsTest.handleAccount(CheckingAccountsTest.java :103)
