Thread: Bank account GUI using swing

Hello AlanM595 and welcome to the Java Programming Forums

I have edited your code and added comments.

There are now 10 Arrays which hold the account information. account1, account2, account3 etc.
Each account array holds 3 values. Name, Account number & Balance.

Every time you add an account, each one of these arrays will be populated until the 10th account is created.
Then the option to create an account is no longer visable.

I have not added the code to delete the accounts but this is just a matter of clearing the account arrays.

I hope this works for you as expected.

Hello AlanM595,

I've edited the code slightly so that the delete button now deletes accounts from the Array.

If you create an account called TEST, you can delete the TEST account by entering the account name and clicking delete.

I've only added the ability to delete from the first 3 accounts. You need to finish it off..

This is actually a pretty messy way to do it but its OK seeing as your a beginner.

I added this to the delete button:

        //Delete accounts which match the account Name
        //Need to finish all the way to account10[]
        if(account1[0] == Name){
            account1[0] = EMPTY;
            account1[1] = EMPTY;
            account1[2] = EMPTY;
            displayJTextArea.setText(Name + " Account Deleted.");
 
        }else
        if(account2[0] == Name){
            account2[0] = EMPTY;
            account2[1] = EMPTY;
            account2[2] = EMPTY;
            displayJTextArea.setText(Name + " Account Deleted.");
 
        }else
        if(account3[0] == Name){
            account3[0] = EMPTY;
            account3[1] = EMPTY;
            account3[2] = EMPTY;
            displayJTextArea.setText(Name + " Account Deleted.");
 
        }

Its basically checking the account arrays to see if the first value matches the Name field. If it does, all the stored values are set back to Empty.

I've entered in all that code but when i press the delete button only the last record that is entered is deleted and not the one with the name that has been entered.
i added in "Name = NameJTextField.getText();" to get the user data but it wouldn't delete any records with that entered.
