记得这是大一结束时老师让交的项目代码，当时在网上搜索了许多残缺不全的源码而且也比较麻烦，所以今天准备分享一下当时自己完善后的代码，自己能力有限，如果有哪位朋友进一步完善的话可以在评论区分享一下谢谢。
1.snakeMain

package Snake5;
import java.awt.Graphics;

import javax.swing.*;
public class snakeMain extends JFrame {
	public snakeMain() {
		snakeWin win = new snakeWin();
		add(win);
		setTitle("贪吃蛇小游戏");
		setSize(435,390);
		setLocation(200, 200);
		setVisible(true);
	}
	public static void main(String[] args) {
		new snakeMain();
	}
}
