java为图形填充颜色

import java.awt.*;import java.awt.event.*;public class painting extends Frame {public painting() {super("painting"); setSize(400,350); setVisible(true); } public static void main(String args[]) {painting app= new painting(); app.addWindowListener(new Handler1()); } public void paint(Graphics g) { g.drawOval(180,180,120,120); } static class Handler1 extends WindowAdapter {public void windowClosing(WindowEvent e) {System.exit(0); } }}所画图形是一个圆，请各位高手大侠们帮下忙，添加代码能将“圆填充为红色”

只需把g.drawOval(...)改成g.setColor(Color.RED); g.fillOval(..)就行了，drawOval是只画不填充，而fillOval是画并且填充，填充的颜色是由g.setColor()方法的参数决定的。
