怎么将applet转变为application

下面是个applet的吃豆子小游戏，怎么把它弄成application啊

5 个解决方案

#1

与楼主一样的问题
一样的豆豆代码
想请问楼主，我的游戏点击空格不反应
玩不了啊？

#2

没人吗。。。。。。。。。。。。。

#3

package Pacgame;

import java.awt.*;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

import javax.swing.JFrame;

public class Run {

public static void main(String[] args) {

  Packman applet = new Packman();  //applet文件名
   JFrame frame = new JFrame("马里奥守护战之穿越时空：豆豆空间");
   frame.addWindowListener(new WindowAdapter() {
     public void windowClosing(WindowEvent e){
       System.exit(0);
     }
   });
   frame.getContentPane().add(
     applet, BorderLayout.CENTER);
   frame.setSize(580,540);//;(650,520);
   applet.init();
   applet.start();
   frame.setVisible(true);

}

}

试一试可行吗？

引用 3 楼 qq_34622559的回复:

package Pacgame;

import java.awt.*;

public class Run {

public static void main(String[] args) {

   frame.setSize(580,540);//;(650,520);
   applet.init();
   applet.start();
   frame.setVisible(true);

}

}

是的，但是我的程序对键盘操作不反应，豆豆不走动，
快绝望死了，怎么调试都不成功。
你的能行吗？
