在applet中在一个矩形中画圆？（我是新手）

Question

题目是：在applet中绘制一个带颜色的矩形，然后在矩形中再画一个圆，圆是另外一种颜色，我试了几个程序，还是只有一个矩形，请问怎么做啊？我是新手哈！下面是我的源代码：（我总是觉得应该用另外一个Graphics对象来画圆。。）
 import java.applet.*;
 import java.awt.*;
 public class G1 extends Applet{
             public void paint(Graphics g)
                            {   
                                Color c= new Color(180,10,120);
                                g.setColor(c);
                                g.drawRect(30,50,300,200);
                                g.fillRect(30,50,300,200);
                                g.drawOval(50,80,80,100);
                                g.fillOval(50,80,80,100);
                                g.setColor(Color.yellow);
                                                           }
            }         

Answer 1

把最后那句 g.setColor(Color.yellow);  提前
先设置颜色，后绘制

Answer 2

其实画了 只不过同一个颜色 你没有看出来
import java.applet.*;
import java.awt.*;
public class G extends Applet{
            public void paint(Graphics g)
                            { 
                                Color c= new Color(180,10,120);
                                g.setColor(c);
                                g.drawRect(30,50,300,200);
                                g.fillRect(30,50,300,200);
                                g.setColor(Color.yellow);
                                g.drawOval(50,80,80,100);
                                g.fillOval(50,80,80,100);
                                
                                                          }
            }
