urlyBird 1.2.3 - customer holding record

[Payal Shah]

For my gui , i have a text box , where use can enter the customer id number.

The spec says it should be 8 digit number?

I am guessing then it should be between 0 through 9 and legth = 8..

I was thinking about doing some kind of screen validation.. extends the Jtextfield and create my custom textfield class..it is out of scope for this exam?

thank you.

Either way, just document your decision. I didn't implement that mechanism.

I did implement it. I have a JTextField, where the user can only insert numbers from 0 to 9, and only up to 8 numbers.

Thank you Jeffry and Roberto.

But to do this you don't have to extend JTextField.
You could use javax.swing.text.MaskFormatter:

   
    MaskFormatter formatter = new MaskFormatter("########");

(The '#' means that just numbers can be inserted).

And than, use it with a JFormattedTextField.
