贪吃蛇由蛇头，蛇身构成，然后需要在画布上随机生成食物，每吃掉一个就要生成新的食物，并且蛇的长度会+1

3.Play
class Play extends Thread{

String music;
public Play(String file) {
this.music = file;
}
public void run() {
try {
play();
} catch (FileNotFoundException | JavaLayerException e) {
e.printStackTrace();//在命令行打印异常信息在程序中出错的位置及原因
}
}
public void play() throws FileNotFoundException, JavaLayerException {
BufferedInputStream buffer = new BufferedInputStream(new FileInputStream(music));
player = new Player(buffer);
player.play();
}
}

项目总结
1.有想要添加的功能，但也是由于上述原因未能实现，比如添加会导致游戏结束的炸弹，蛇的移动速度随着长度的增加变快或是变慢，随着游戏时间的增加让画布上的食物越来越多等。
2.背景音乐只能实现一打开游戏就播放，音量也是跟随系统音量并不能改变，不能实现暂停或者切换下一首等音乐器的基本操作
