Also an additional button that fill the rect and ovals how can I do that because I have not idea I have try everything and nothing works. please help me here is my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class mouseDraw extends JApplet implements MouseListener, MouseMotionListener, ActionListener
{
private int mouseX, mouseY, mouseY1, mouseX1;
private JButton[] buttons = new JButton[4];
private JPanel controlPanel, drawPanel;
private int shape;
public void init()
{
buttons[0] = new JButton("Line");
buttons[1] = new JButton("Rectangle");
buttons[2] = new JButton("Oval");
buttons[3] = new JButton("Fill");
buttons[0].setBackground(Color.red);
controlPanel = new JPanel();
controlPanel.setLayout(new FlowLayout());
controlPanel.setBackground(Color.orange);
drawPanel = new JPanel();
drawPanel.setBackground(new Color(0xffffcc));
for (int i=0; i<4; i++)
controlPanel.add(buttons[i]);
Container pane = getContentPane();
pane.setLayout(new BorderLayout());
pane.add(controlPanel, BorderLayout.NORTH);
pane.add(drawPanel, BorderLayout.CENTER);
for (int i=0; i<4; i++)
buttons[i].addActionListener(this);
addMouseListener(this);
addMouseMotionListener(this);
}
public void paint(Graphics g)
{
super.paint(g);
int x = Math.min(mouseX1, mouseX);
int y = Math.min(mouseY1, mouseY);
g.setColor(Color.blue);
int w = (int)Math.abs(mouseX1 - mouseX);
int h = (int)Math.abs(mouseY1 - mouseY);
switch (shape)
{
case 0: g.drawLine(mouseX1, mouseY1, mouseX, mouseY);
break;
case 1: g.drawRect(x, y, w, h);
break;
case 2: g.drawOval(x, y, w, h);
break;
case 3: g.fillRect(x, y, w, h);
break;
}
}
public void mouseMoved(MouseEvent e)
{
mouseX = e.getX();
mouseY = e.getY();
showStatus("Mouse is moved to (" + mouseX + mouseY + ")");
}
public void mouseDragged(MouseEvent e)
{
mouseX = e.getX();
mouseY = e.getY();
showStatus("Mouse is moved to (" + mouseX + mouseY + ")");
repaint();
}
public void mouseEntered(MouseEvent e)
{
}
public void mouseExited(MouseEvent e)
{
}
public void mouseReleased(MouseEvent e)
{
}
public void mousePressed(MouseEvent e)
{
mouseX1 = mouseX;
mouseY1 = mouseY;
}
public void mouseClicked(MouseEvent e)
{
}
public void actionPerformed(ActionEvent e)
{
for (int i=0; i<4; i++)
{
buttons[i].setBackground(Color.lightGray);
if (e.getSource() == buttons[i])
{
shape = i;
buttons[i].setBackground(Color.red);
}
}
}
}

Heck, you haven't even tried the suggestion from A. Wolf in this thread.. This is your 6th post in two days asking for someone to do your homework. You will get better results if you ask a specific question (i.e. how do I draw a square using the mouse on a JPanel) than just posting your code and hoping someone finishes it for you.
