meliaht pointering mouse pada piksel x dan y

11.      Buat program untuk membuat frame kosong, dimana setiap pergerakan pointering / penunjuk mouse yang melewati area frame tersebut, maka posisi piksel x dan y dari pointer ditampilkan.

Program :

import javax.swing.*;

import java.awt.*;

import java.awt.event.*;

class mouse extends JFrame implements MouseListener,MouseMotionListener{

            JTextArea a;

            mouse(){

                        super ("Pergerakan Mouse");

                        setSize(400,400);

                        a =new JTextArea (3,20);

                        a.setEditable(false);

                        JPanel c=new JPanel();

                        c.add(a);

                        getContentPane().add(c);

                        c.addMouseListener(this);

                        c.addMouseMotionListener(this);

                        show();

            }

            public void mouseClicked(MouseEvent b){}

            public void mousePressed(MouseEvent b){}

            public void mouseMoved(MouseEvent b){

                        String d;

                        d = "Posisi Mouse \n Posisi X = "+b.getX()+"\n Posisi Y = "+b.getY();

                        a.setText(d);}

            public void mouseReleased(MouseEvent b){}

            public void mouseEntered(MouseEvent b){}

            public void mouseExited(MouseEvent b){}

            public void mouseDragged(MouseEvent b){}

            public static void main (String[] args) {

                        mouse oby = new mouse();

}

}
