Confirm Dialogs

It's not very nice to ask a question, and then only give one option for an answer. So there's also a Confirm Dialog, where we can specify more buttons be made available:

package swingExamples;

import javax.swing.JOptionPane;

public class SimpleConfirm1
{
  public static void main(String[] args)
  {
    JOptionPane.showConfirmDialog(
        null, // The parent frame
        "Are you sure you want to do this?", 
              // a message
        "Just checking...", // a title
        JOptionPane.YES_NO_OPTION, 
                      // The option type
        JOptionPane.QUESTION_MESSAGE 
                      // the message type
        );
  }
}

which produces:

Now, we'd like to know how the user answered, so we can do the following:

package swingExamples;

import javax.swing.JOptionPane;

public class SimpleConfirm2
{
  public static void main(String[] args)
  {
    int status = JOptionPane.showConfirmDialog(
        null, // The parent frame
        "Are you sure you want to do this?", 
              // a message
        "Just checking...", // a title
        JOptionPane.YES_NO_OPTION, 
                      // The option type
        JOptionPane.QUESTION_MESSAGE 
                      // the message type
        );
    if (status == JOptionPane.YES_OPTION)
    {
      System.out.println("You said Yes!");
    }
    else if (status == JOptionPane.NO_OPTION)
    {
      System.out.println("You said No!");
    }
  }
}

which produces the following, after the user responds by clicking on the No button:

You said No!

Now, sometimes it's necessary to give the user a third choice: Yes, No, or Cancel, so here's how you would do that:

package swingExamples;

import javax.swing.JOptionPane;

public class SimpleConfirm3
{
  public static void main(String[] args)
  {
    int status = JOptionPane.showConfirmDialog(
        null, // The parent frame
        "Are you sure you want to do this?", 
              // a message
        "Just checking...", // a title
        JOptionPane.YES_NO_CANCEL_OPTION, 
              // The option type
        JOptionPane.QUESTION_MESSAGE 
              // the message type
        );
    if (status == JOptionPane.YES_OPTION)
       System.out.println("You said Yes!");
    else if (status == JOptionPane.NO_OPTION)
       System.out.println("You said No!");
    else if (status == JOptionPane.CANCEL_OPTION)
       System.out.println("You cancelled!");
  }
}

which produces:

and in response to the user clicking on Cancel, the program prints out:

You cancelled!
