Is there a way to move mouse coordinates to the title of the JFrame?

Got method paint() to draw mouse coordinates in JFrame in coordinates x=20, y=20. Is there a way to move rendering mouse coordinates to the title of the JFrame? Try to use jFrame.setTitle() but it want String as parametr.

 jFrame.setTitle(g.drawString("Coordinates x:" + xCord + " y" + yCord, 20, 20)) not work.

Here is my code:

 private static void paint() {
        JComponent jComponent = new JComponent() {
            @Override
            protected void paintComponent(Graphics g) {
                super.paintComponent(g);
                Font font = new Font("Comic Sans MS", Font.BOLD, 20);
                g.setFont(font);
                g.drawString("Coordinates x:" + xCord + " y" + yCord, 20, 20);

            }
        };

        jFrame.add(jComponent);
        jFrame.addMouseMotionListener(new MouseAdapter() {
            @Override
            public void mouseMoved(MouseEvent e) {
                super.mouseMoved(e);
                xCord = e.getX();
                yCord = e.getY();
                jComponent.repaint();
            }
        });
    }

Here's a simple example of a GUI that updates the title of the JFrame.

I just updated the title String with the coordinates from the mouseMoved method of the MouseMOtionListener.

Here's the runnable, contained, example.

import java.awt.Dimension;
import java.awt.Point;
import java.awt.event.MouseEvent;
import java.awt.event.MouseMotionListener;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class MouseCoordinatesTitle implements Runnable {
public static void main(String[] args) {
SwingUtilities.invokeLater(new MouseCoordinatesTitle());
}
private JFrame frame;
private String title;
public MouseCoordinatesTitle() {
this.title = "Coordinates: ";
}
@Override
public void run() {
frame = new JFrame(title);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(createMainPanel());
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
private JPanel createMainPanel() {
JPanel panel = new JPanel();
panel.setPreferredSize(new Dimension(600, 400));
panel.addMouseMotionListener(new PositionListener());
return panel;
}
public void updateJFrameTitle(Point point) {
StringBuilder builder = new StringBuilder(title);
builder.append("X: ");
builder.append(point.x);
builder.append(", Y: ");
builder.append(point.y);
frame.setTitle(builder.toString());
}
public class PositionListener implements MouseMotionListener {
@Override
public void mouseMoved(MouseEvent event) {
Point point = event.getPoint();
updateJFrameTitle(point);
}
@Override
public void mouseDragged(MouseEvent event) {
}
}
}
