Confirm Dialog in Swing
import javax.swing.JOptionPane;
public class JOptionDialog {
public static void main(String[] args) {
JOptionPane.showConfirmDialog(null, "Are you sure?", "Example 4",
JOptionPane.YES_NO_CANCEL_OPTION);
}
}
Finally, let’s use a JOptionPane constructor and place the new pane inside a regular Swing container. This is a strange thing to do, but it’s perfectly valid
import java.awt.*;
import javax.swing.*;
public class JOptionDialog {
public static void main(String[] args) {
JFrame f = new JFrame( );
Container c = f.getContentPane( );
c.setLayout(new BorderLayout( ));
JOptionPane op = new JOptionPane("Stop!", JOptionPane.WARNING_MESSAGE);
JPanel p = new JPanel(new FlowLayout( ));
p.add(op);
c.add(p);
c.add(new JLabel("Example 6", JLabel.CENTER), BorderLayout.NORTH);
f.setSize(200,200);
f.setVisible(true);
}
}
