Compile error in paint() method while trying to draw graphics

Question

Hi ,
I am trying to draw two lines given the sceen coordinated through a mouse click. I am getting the following error
Pos.java:90: illegal start of expression
public void paint(Graphics g)
^
Pos.java:102: ';' expected
^
2 errors
My code is as follows:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.geom.*;
public class Pos extends Container {
//public void paint(Graphics);
public static void main(String args[]) {
Pos p = new Pos();
     p.getPosition();
JButton bn = new JButton("Draw Line");
int posx=0;
int posy=0;
int i=0;
int x[] = new int[4];
int y[] = new int[4];
public void getPosition() {
JFrame frame = new JFrame("Mouse Position");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JLabel label = new JLabel();
label.setHorizontalAlignment(JLabel.CENTER);
/*MouseMotionListener mouseMotionListener = new MouseMotionListener() {
public void mouseDragged(MouseEvent e) {
public void mouseMoved(MouseEvent e) {
          MouseListener mouseListener = new MouseListener(){
               public void mouseEntered(MouseEvent evnt){
               public void mouseExited(MouseEvent evnt){
               public void mousePressed(MouseEvent evnt){
               public void mouseReleased(MouseEvent evnt){
               public void mouseClicked(MouseEvent evnt) {
                    showMousePos(evnt);
                    //mon.setText("("+MouseInfo.getPointerInfo().getLocation().x+","+
                                        //MouseInfo.getPointerInfo().getLocation().y+")");
               private void showMousePos(MouseEvent evnt) {
JLabel src = (JLabel)evnt.getComponent();
               posx = MouseInfo.getPointerInfo().getLocation().x;
               posy = MouseInfo.getPointerInfo().getLocation().y;
System.out.println("x-coordinate="+posx);
               System.out.println("y-coordinate="+posy);
               x=posx;
               y[i]=posy;
               i=i+1;
          label.addMouseMotionListener(mouseMotionListener);
          label.addMouseListener(mouseListener);
          label.addActionListener(actionListener);
frame.add(label, BorderLayout.CENTER);
          bn.setSize(10,10);
          frame.add(bn, BorderLayout.NORTH);
frame.setSize(300, 300);
frame.setVisible(true);
     ActionListener actionListener = new ActionListener(){
               public void actionPerformed(ActionEvent ae)
                    Object o = ae.getSource();
                    if (o==button)
                         public void paint(Graphics g)
                              Graphics2D g2D = (Graphics2D)g;
                              //int p[]=new int[4];
                              g2D.setColor(Color.red);
                              //for (int j=0;j<2;j++)
                                   //Point2D.Int p[j]= new Point2D.Int(x[j],y[j]);                              
                              //Line2D line = new Line2D.Int(p[0],p[1]);
                              g2D.drawline(x[0],y[0],x[1],y[1]);
                              i=0;
Please tell me what the mistake is.

Thank you all for the sggestions. The error was exactly due to what you mentioned above. I fixed that by drawing the lines on another JPanel and it is working now.
But I have a bigger problem. How to make a JPanel transparent. I have to draw lines on a video. The panel for drawing lines is opaque and so I can draw lines only if I am able to see the video. setOpaque(false) does not seem to work. I am posting my code below. Please see if you can help me out.
