By creating your custom dialogs. If you look at the source code of JOptionPane, you'll notice that it's just a JComponent with some predefined controls shown inside a JDialog.

Now I got this, but the line class solve extends JFRame implements ActionListener { doesnt work

import javax.swing.JOptionPane;
import java.awt.event.*;
import java.awt.*;
import javax.swing.*;

class solve extends JFrame implements ActionListener {
    static JFrame frame;
    public static void main(String[] args) {
        frame = new JFrame("Test");
        solve solve = new solve();
        JPanel panel = new JPanel();

        frame.setSize(400,400);
        JButton b = new JButton("click");

        b.addActionListener(solve);
        frame.add(b);
        frame.add(panel);

        frame.show();
    }
}
