贪食蛇的实现源码

package awt;
import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
public class AWTFramec {
    private Frame f;
	private Label lab;
	private Button bu1,bu2;
	private Panel pan;//得初始化要不我想的出现java.lang.NullPointerException
	public void go()
	{
		f=new Frame("example");
		lab=new Label("视频");
		bu1=new Button("打开");
		bu2=new Button("关闭");
		pan=new Panel();
		f.setLayout(new BorderLayout());
		pan.setLayout(new FlowLayout(FlowLayout.CENTER));
		f.add(BorderLayout.NORTH,lab);
		f.add(BorderLayout.CENTER,pan);
		pan.add(bu1);
		pan.add(bu2);
		f.addWindowListener(new WindowAdapter(){
			public void windowClosing(WindowEvent evt){
				f.setVisible(false);
				f.dispose();
				System.exit(0);
			}
		});
		f.setBounds(100,100,500,200);
	   pan.setSize(5000, 2000);
		f.setVisible(true);
		
	}
	public static void main(String[] args) {
		AWTFramec awt=new AWTFramec();
		awt.go();
