达内学习心得：和TTS 有所不同的贪吃蛇 能穿墙而不是撞墙参赛人:陈彬豪获得奖项:三等奖内容： 第一步，就是先把单个格子的属性创建出来public class Cell int row; int col; int color; static int indexRow = 10000;/这个参数是上下穿墙用的，为了保证不用完，要尽可能的大 static int indexCol = 10000;/这个参数是左右穿墙用的，为了保证不用完，要尽可能的大 public Cell()/对于父类，无参数构造器不一定用到，应该习惯的写上 public Cell(int x, int y, int color) super(); this.row = x; this.col = y; this.color = color; /各属性的get set方法 public int getColor() return color; public void setColor(int color) this.color = color; public int getRow() return row; public void setRow(int x) this.row = x;
