Rotation the image moves towards upper left

Hello,

here is the class file for rotation, as the image rotates it moves towards left, should stay stable or rotate around the mentioned co ordinates

package draw;

import java.awt.*;
import java.awt.image.BufferedImage;

public class Rotation extends java.applet.Applet {

final static int BALL_RADIUS = 45;

BufferedImage ball = null;

public void init()
{
    ball = new BufferedImage(BALL_RADIUS, BALL_RADIUS, BufferedImage.TYPE_INT_RGB);
            
    Graphics ballG = ball.getGraphics();   
         
    ballG.setColor(Color.white);
            
    for(int i=-20;i<=0;i++)
    {
     ballG.drawOval(i, i, BALL_RADIUS + ((-i)*2), BALL_RADIUS + ((-i)*2));                    
    }
}   

public void paint(Graphics g)
{
    float angle = 0;
    double speed =  0.1;
    int x = 140;
    int y = 140;
    for(int c=0;c<1600;c++)
    {
    float radius = 4;           
    x = (int) (x + Math.cos(angle) * radius);
    y = (int) (y + Math.sin(angle) * radius);
    angle += speed;        
    g.fillRect(42, 45, getBounds().width, getBounds().height);
    g.setColor(Color.white);        
    g.drawImage(ball, x, y, this);             
    delay(25);    
}
    System.out.println("paint() done");

}

private void delay(int millis)
{
    try{Thread.sleep(millis);}catch(Exception ignored){}       
}

}
