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

hi,
I think the problem is the use of "CheckingAccount.getAccountType" etc. in different calls to System.out.printf .
all other parameters are "currentAccount.get..."
Try to change the first in the latter and try again.
bye,

Start at the line number given in the exception and work back from there.
You're trying to call a method on an unitialised object reference, something that's impossible.
Once you know what reference that is, work back to find out why it's not initialised (or maybe you're working with the wrong one?).

there is another mysterious statement, namely:

after the while, in both handleAccounts, after the first '{'

xxx.equals(yyy);

in my humble opinion that isn't a statement! (otherwise : what does it mean?)
I wonder how you got through the compiler...

I tried to copy the lot, as to try it myself, but there is too much code missing (classes and so on)

by the way....
1. is there a manner to get java text from the code into your (my) own (java) environment??...copy & paste gives one endless line without carriage-returns)
2. if you feel like it, sent me all you have, as an attachment, I like a challenge.
3. I hate this kind of 'generated' code, it is almost unreadable (while the opposite is intended, I suppose).
4. I use the jGRASP-shell for JAVA, and can strongly recommend it
(www.jgrasp.com)
5. ?

good luck,
peter
