3 Class Investment Account

Question

I am writing a three class Investment Account program with the three classes being AccountInterface, AccountModel and Account.
One of the butttonclick options is to save the data entered for a certain account (name, age, deposit, rate)
Without using arrays you need to be abkle to enter the details for two different bank accounts, so in the interface you add the deatils for one, click add and it stores the data for the account, then when you clear this and add data for a new bank account it needs to check if there is anything for account 1 if yes, then add the details for account two.
I am struggling with this.
Can someone point me in the right direction of where to start with this? I know that the button click in the AccountInterface needs to call a method from AccountModel.

Your problem is very specific to the homework assignment it comes from, and you're not describing your homework assignment very well. Perhaps someone here can give you specific advice but I doubt it.
So here's some general advice:
First, separate your GUI from the application logic. Thinking about button clicks and event handlers and such will just get in the way of understanding the problem to be solved. Try writing a test class (or several) that you can execute from the command line, and that will act as a hardcoded single scenario, that will invoke the application logic code. So an example test might do a single "add" operation. Then write code that will satisfy this test class.
Secondly, make certain you understand the problem before you try to solve it. Draw diagrams, use Legos, whatever, to give yourself something tangible to work with. Once you're able to express the problem well, you're two-thirds of the way to solving it. A lot of homework just involves rephrasing what the prof said to make it make sense.
And if all else fails, as your prof for clarification.
