public void paint(Graphics g) {


Thread t =Thread.currentThread();
Rectangle r = getBounds();

int hlines = r.height / 30;
g.setColor(Color.red) ;
g.fillRect(0,0,r.width ,r.height);

g.setColor(Color.black);
for (int i = 1; i <= r.height/30; i++) {
g.drawLine(30, i * 30, r.width, i * 30);
g.drawString( String.valueOf(r.height-i * 30) , 0 ,i*30);
Thread.sleep(1000);
}


for (int i = 1; i <= r.width/30; i++) {
g.drawLine(i * 30,0 , i* 30, r.height-30);
g.drawString( i * 30+"", i* 30, r.height);
}
