I have a problem in this java code.
I want to make a painter program but whenever I choose a shape and draw it 
all the shapes that were drawn before become the same as this shape. Here's the code.
I know that the problem is from the for statement in the `paintComponent` but what can I replace it with?

```
class inner extends JPanel implements MouseListener,MouseMotionListener{
        private int oldx,oldy,newx,newy;
        private Point point1,point2;
        private Shape newRec,line1;
        Rectangle currRec;
        private Vector shape;
        private boolean status,status1;
        private int count=0;
        private Object line;
        inner(){
            point1=point2=new Point(0,0);
            shape = new Vector();
            addMouseListener(this);
            addMouseMotionListener(this);
        }

        public void mouseDragged(MouseEvent event) {

            point2=event.getPoint();
            newx = point2.x;
            newy = point2.y;
            if(Universal==7){
            line = new Object(oldx,oldy,newx,newy);
            status = true;
            repaint();
            }

            currRec = new Rectangle(Math.min(point1.x,point2.x),Math.min(point1.y,point2.y),Math.abs(point1.x-point2.x),Math.abs(point1.y-point2.y));   
            status = true;
            repaint();

        }

        @Override
        public void mouseMoved(MouseEvent arg0) {}

            newx=event.getX();
            newy=event.getY();
            //count++;

                line1 = new Shape(point1.x,point1.y,point2.x,point2.y);
                shape.add(line1);
                //Graphics g = getGraphics();
                //g.setColor(colour);
                //g.drawLine(point1.x,point1.y,point2.x,point2.y);
