[gautamz07]

import java.awt.*;
import javax.swing.*;
import java.swing.JFrame;

public class DisplayMouseCoordinates extends JFrame implements MouseMotionListener 
{
JLabel displayCoords;

public DisplayMouseCoordinates()
{
Container cp=getContentPane();
JPanel panel=new JPanel();
displayCords=new JLabel();
panel.add(BorderLayout.CENTRE, displaycoords);
cp.add(panel);
setVisible(true);
setSize(500,500);
setTitle("Demo of mouse co-ordinates");
panel.addMouseMotionListener(this);
setLocationRelativeTo(null);
}
public static void main(String args[])
{
DisplayMouseCoordinates cords=new DisplayMouseCoordinates();

}
public void MouseDragged(MouseEvent args0)
{
public void MouseMoved(MouseEvent Me)
{
String data= "(x: "+me.getx() + "," + "y:" + me.gety() + ")";

displayCords.setText("co-ordinates:" + data);
}
}

String data= "(x: "+me.getx() + "," + "y:" + me.gety() + ")";

It's just creating a string by concatenating strings with other values.
