I got the following error in my compiler for this driver code:

.\MyLines.java:25: cannot find symbol
symbol : method paintComponet(java.awt.Graphics)
location: class javax.swing.JPanel
super.paintComponet (g);

Its paintComponent(...).

Having said that I would advise you to use this strategy instead,
(and forget about super methods invokation):

public void update (Graphics g) {
  Color c=g.getColor();  // remember context color
  g.setColor(Color.lightGray);
  g.fillRect(0,0,getSize().width, getSize().height);
  int v1;
  int v2;
  v1 = startingx;
  v2 = startingy;
  g.setColor(Color.red); // or any other color,  except lightGray
  while (v1 <= getWidth()) {
    g.drawLine(v1, v2, v1 + startingl, v2);
    v1 += startingl;
    g.drawLine(v1, v2, v1, v2 + startingl);
    v2 += startingl;
  }
  g.setColor(c); // restore context color
}
public void paint(Graphics g) {
  update(g);
}

PS: never invoke the paint() method from the update() method, it will never finish....
