drawing array of lines

[Norgy]

i am trying to draw an array of lines where the user will be able to draw multiple lines
here is the code but it is not working well and i don't know why

import java.applet.Applet;
import java.awt.Graphics;
import java.awt.event.MouseAdapter;
import java.awt.Color;
import java.awt.event.MouseMotionListener; 
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
 
 
public class MultipleLineClass extends Applet{
    int x1,y1,x2,y2;
    MyLine[] obj = new MyLine[5];
    int i=0;
    public void init(){
        addMouseListener(new MyButtonListener());
        addMouseMotionListener(new MyButtonListener());    
 
    }
    public void paint(Graphics g){
        for(int j=0 ; j<i ; j++){
            g.setColor(Color.red);
            g.drawLine(x1,y1,x2,y2);
        }
    }
    class MyButtonListener extends MouseAdapter implements MouseMotionListener,MouseListener{
        public void mousePressed(MouseEvent e){ 
            x1 = e.getX();
            y1 = e.getY();
        }
        public void mouseDragged(MouseEvent e){
            x2 = e.getX();
            y2 = e.getY();
            obj[i] = new MyLine(x1,y1,x2,y2);
            i+=1;
            repaint();
        }
        public void mouseMoved(MouseEvent e){}
    }
 
    class MyLine{
 
        MyLine(int xx1, int yy1, int xx2, int yy2){
            x1=xx1;
            x2=xx2;
            y1=yy1;
            y2=yy2;
        }
 
    }
 
}

    int i=0;
    public void init(){
        addMouseListener(new MyButtonListener());
        addMouseMotionListener(new MyButtonListener());    
 
    }

        if(i<10){
            for(int j=0 ; j<i ; j++){
                g.setColor(Color.red);
                g.drawLine(obj[j].getX1(),obj[j].getY1(),obj[j].getX2(),obj[j].getY2());
            }
        }
    }

            y2=yy2;
        }
        public int getX1(){return x1;}
        public int getX2(){return x2;}
        public int getY1(){return y1;}
        public int getY2(){return y2;}
 
 
    }
