求贪吃蛇java程序代码(要能运行的,有完整注释的)

三个文件，楼主看好：
运行可以，但是并不能鼓吹是一个具有好的风格的代码，。
//文件一
package greedysnake_cx;
public class Node {
int x=0;
int y=0;

int nodewidth;
int nodeheight;

Node(int x,int y){
thisx=x;
thisy=y;
}
}
//文件二
package greedysnake_cx;

实现一个greedysnake的模型，具有功能：
1）移动，moveOn（）－－－－从director参数中获取方向信息，如果方向定义的下一个点的逻辑值是true，检查是不是food，是则将food添加到
列表的头部，snake继续移动，不是则停止移动（撞到蛇尾巴了）
2）加速，speedUp()－－－－将现成的停滞时间间隔interval按照一定的比率 speedRate进行扩大
3）减速，speedDown()－－－－

该类实现Runnable接口，
/

创建一个随机数的生成器，这个是javautilRandom类
与javalangMath类中的random()方法有不一样的地方，彼方法返回一个0－1之间的随机数
