Question

I don’t know how to insert a line of code that counts the numbers entered in a box that pops up. Basically I can’t enter more than 5 numbers. So I think some sort of if statement needs to be inputed, which I don’t know how to do.

Here is my code:

String number;


number = JOptionPane.showInputDialog("Enter Number");       


JOptionPane.showMessageDialog(null,"The new result is" + number,"Results",
        JOptionPane.PLAIN_MESSAGE);

        System.exit(0);

Thanks

EDIT: a little shabby but how about something like this?

while(true)
{
    String number = JOptionPane.showInputDialog("Enter Number");       

    if(number.length() >5 )
    {

        JOptionPane.showMessageDialog(null ,"Too Long! try again",JOptionPane.PLAIN_MESSAGE);
    }
    else break;
}
