Having problems with assignment

Question

Hello all, I'm fairly new to java and finding this assignment quite hard as Ive had no assistance with it from my trainer.
In a brief description, its has to work like a financial system, where a user inputs several numbers into a JOptionPane.showInputDialog and they are displayed down in a JtextArea. At the bottom these inputs need to be added up. Below I have pasted what Ive done so far, as I said I�m still new to java. I have not added the calculate part but it should be located under the final text area.
The major difficulty I�m having at the moment is displaying the inputs from the user into the Jtextarea created.
Here is the code, cut and paste to run (hopefully this will show u more what I�m talking about.
When i tested this i get [Ljava.lang.String;@46cbe9ee in the program, i dont know why this is comming up, but under AccountName and AccountNo.  the static names that have been decleared should be displaying, and under debit and account there should be nothing there till user has inputed it.
