ShowInputDialog as condition in a loop

Question

Hi,
I'm trying to do a loop that pops out showInputDialog
The loop should stop when user presses Cancel or the "X" button on the dialog ;[
Any idea how this could be done ?
something like
String input = "";
while((input = JOptionPane.showInputDialog("some text: ")) != ???)
what should I compare it to ?
non of the JOptionPane.CANCEL_OPTION or JOptionPane.CLOSE_OPTION work as InputDialog returns a String not an Integer ;(
So my question is how can I break the loop using the 'cancel' or 'x' button on the dialog ???
Help !

Answer 1

Would something like this work?
import javax.swing.JOptionPane;
public class Fubar
    public static void main(String[] args)
        String input = "";
        boolean inputDone = false;
        while (!inputDone)
            input = JOptionPane.showInputDialog("This is some text");
            if (input != null)
                // do what you want to do with the input
                System.out.println(input);
            else
                // tell the while loop: "OK, I'm done"
                inputDone = true;
}Also, when posting your code, please use code tags so that your code will be well-formatted and readable. To do this, either use the "code" button at the top of the forum Message editor or place the tag [code] at the top of your block of code and the tag [/code] at the bottom, like so:
[code]
  // your code block goes here.
