public void drawCenteredCircle(Graphics2D g, int x, int y, int r) {
x = x-(r/2);
y = y-(r/2);
g.fillOval(x,y,r,r);
}

window.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
window.setVisible(true);
DrawingComponent DC = new DrawingComponent();
window.add(DC);
}
}
class DrawingComponent extends JComponent{
public void paint(Graphics graph0){
Graphics2D graph = (Graphics2D) graph0;
Ellipse2D.Double circle = new Ellipse.Double(5, 5, 25, 25);
graph.fill(circle);
}
}
