Thread: Bank Account

Hello! I'm having some difficulty with my bank account project. I'm supposed to create a menu where the user can create a new account, withdraw, deposit, view their balance, and exit. There's issues with the account creation. Can someone please help me fix this problem?

Here's my necessitated class below: BankAccount, TestBankAccount, SavingsAccount, CurrentAccount, and Bank

There's issues with the account creation.

What issue? Post the error message, describe the issue, post a sample run. Give us something to understand what you're trying to fix.

OK, for the account, I have to enter my name. The program then generates a random 4 digit ID number and a random 4-letter string which serves as a password. Every time I do so, The program either 1.)only displays the name, 2.)terminates, 3.)throws an Input Mismatch or Array Out of Bounds Exception, or 4.)loops infinitely back to the main menu, skipping the block entirely.

Add print statements to the code to determine which methods are being run, what their inputs and outputs are and to ultimately determine why the logic flow you think the program should follow isn't being followed.

If you wrote all of this code before doing any testing, you're doing it wrong. You should have written and tested each menu choice before writing the next. Keep the amount of untested code as small as possible, make small changes, and test the changes to ensure the desired results have been achieved.
