JOptionPane - confirm Example
The Confirm dialog type is called from the method showConfirmDialog() which asks a question and displays answer buttons, usually Yes, No, and Cancel. The program displays each of the dialog types. Here we show it displaying the message for type JOptionPane.DEFAULT_OPTION and a null title.
// JoptionPane showConfirmDialog Example
import javax.swing.*;
class JOptionPaneExample2 {
static void show(String s, String title, int type) {
int reply = 0;
if(title==null) {
reply=JOptionPane.showConfirmDialog(null, s);
}
else {
reply = JOptionPane.showConfirmDialog(null, s, title, type);
}
switch(reply) {
case JOptionPane.YES_OPTION: // same as OK_OPTION
System.out.println("YES/OK selected"); break;
case JOptionPane.NO_OPTION:
System.out.println("NO selected"); break;
case JOptionPane.CANCEL_OPTION:
System.out.println("CANCEL selected"); break;
case JOptionPane.CLOSED_OPTION:
System.out.println("CLOSED selected"); break;
default: break;
}
}
public static void main(String[] args) {
String s = "The question is: why did you do it?";
String title = "Title";
show(s, null, JOptionPane.DEFAULT_OPTION);
show(s, title, JOptionPane.DEFAULT_OPTION);
show(s, title, JOptionPane.YES_NO_OPTION);
show(s, title, JOptionPane.YES_NO_CANCEL_OPTION);
show(s, title, JOptionPane.OK_CANCEL_OPTION);
System.exit(0);
}
