如何获取Java Swing中附加的JoptionPane的按钮和动作侦听器？

Question

Here is the simple code that has two JoptionPane . currently, it has no buttons, but I want to attach button to the second JOptionPane for Yes or NO event. Moreover, when the two JOptionPanes are closed, the Frame does not close.Is there a way to force close Frame when JoptionPanes are closed.

here is my current code

import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class TestJoption {

    public static void main(String[] args){

        JFrame frame = new JFrame("Game");

        JOptionPane.showMessageDialog(frame, "You Won!", "Winner", JOptionPane.INFORMATION_MESSAGE);
        JOptionPane.showMessageDialog(frame, "yes No", "play again", JOptionPane.INFORMATION_MESSAGE);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);

    }
}

Answer 1

You can do it like this:

JOptionPane.showConfirmDialog(frame, "yes No", "play again", JOptionPane.YES_NO_OPTION);

this is popup the box with yes and no options..

Answer 2

I think you need next code:

    JOptionPane.showMessageDialog(frame, "You Won!", "Winner", JOptionPane.INFORMATION_MESSAGE);
    int result = JOptionPane.showConfirmDialog(frame, "yes No", "play again",JOptionPane.YES_NO_OPTION);
    if(result == JOptionPane.NO_OPTION){
        frame.dispose();
    }

Answer 3

For closing the window you can either use

frame.setVisible(false);

or you can simply call

System.exit(0);

this will terminate your process.
