Display Menu

[Newbie23]

Hi All

I'm a total newbie to Java.

I'm creating a very simple banking system as a college project. I'm doing ok... logging in the user, the displaying a Main Menu with options to select from. However Im using a If statement for the selection and once I have selected an option (for example = check account balance) I cant go back to the Main Menu (unless I write the whole thing out again, which would be daft).

I have tried to write a method (?) to display the menu, I can then put this at the end of my if statement to return the user to the Main Menu. However I can get it to work... Below is my menu code and below that the code i attempted for the method, if I can resolve this then im pretty much flying at the minute its the only thing holding me back!!!

//Show menu and get users choice
        accChoice = JOptionPane.showInputDialog(null, "Account Menu \n" +
                                          "What would you like to do? \n" +
                                          " 1 - Check Balance.\n" +
                                          " 2 - Make A Withdrawl.\n" +
                                          " 3 - Make A Deposit.\n"+
                                          " 4 - Amend Overdraft.\n" +
                                          " 5 - Exit.\n" +
                                          "Please enter your choice:");
 
    //direct users choice
        if (accChoice.equals(accChoice1))
        {
            System.out.println("1 - Check Balance.");
        }
        else if (accChoice.equals(accChoice2))
        {
            System.out.println("2 - Make A Withdrawl");
        }
        else if (accChoice.equals(accChoice3))
        {
            System.out.println("3 - Make A Deposit.");
        }
        else if (accChoice.equals(accChoice4))
        {
            System.out.println("4 - Amend Overdraft.");
        }
        else if (accChoice.equals(accChoice5))
        {
            System.out.println("5 - Exit");
        }

below is my method(s) code:

private String displayMainMenu()
    {
        String accChoice;
        accChoice = JOptionPane.showInputDialog(null, "Account Menu \n" +
                                          "What would you like to do? \n" +
                                          " 1 - Check Balance.\n" +
                                          " 2 - Make A Withdrawl.\n" +
                                          " 3 - Make A Deposit.\n"+
                                          " 4 - Amend Overdraft.\n" +
                                          " 5 - Exit.\n" +
                                          "Please enter your choice:");
        return accChoice;
 
   }

If you can wait one more day or so then I'll post a little article about this topic because I've seen people struggle with this item more than often. The solution (which you can reuse over and over again!) will be a bit of code that represents a single menu item as well as an entire menu. You can nest menus at will and put in "back" and "quit" menu items whereever you want.

kind regards,

Jos

edit: done; read the 'insights' section of the Java forum: it contains a little article about this very topic.
