import java.awt.Color;import java.awt.Frame;import java.awt.Panel;public class FramePanel extends Frame{public FramePanel(String str){super(str);}public static void main(String args[]){FramePanel frame=new FramePanel("Frame with Panel");Panel panel=new Panel();frame.setSize(200, 200);frame.setBackground(Color.gray);frame.setLayout(null);panel.setSize(100,100);panel.setBackground(Color.red);frame.add(panel);frame.setVisible(true);//使程序可见，在所有程序写完之后执行}}
