java写的简单贪吃蛇，用Eclipse打开，解压可见源码

编函数 float fun(double h)，函数的功能是：对变量h中的值保留两位小数，并对第三位进行四舍五入(规定h中的值为正数)。 例如：若h 值为8.32433，则函数返回8.32 若h值为8.32533，则函数返回8.33。 -Function for float fun (double h), the function of function: The value of the variable h in the retention of two decimals, and rounding to the third (of the value of h provides a positive number). For example: If the h value of 8.32433, the function returns 8.32 if the h value of 8.32533, the function returns 8.33.

MAX7219驱动LED特好使.MAX7219是微处理器和共阴极七段― ― 八位LED显示、图条／柱图显示或64点阵显示接口的小型串行输入／输出芯片。片内包括BCD译码器、多路扫描控制器、．字和位驱动器和8X 8静态RAM。外部只需要一个电阻设置所有LED 显示器字段电流。MAX7219和微处理器只需三根导线连接，每位显示数字有一个地址由微处理器写入。允许使用者选择每位是BCD 译码或不译码。使用者还可选择停机模式、数字亮度控制、从1～8选择扫描位数和对所有LED显示器的测试模式。-LED Driver MAX7219 so special. MAX7219 is a microprocessor and a total cathode seventh-- 8 LED display, map article/column or 64 shows a small dot-matrix display interface serial input/output chips. Chip including the BCD decoder, multiplex scan controller. Word and bit drive and 8X 8 static RAM. External resistor only need one set all LED displays current field. MAX7219 and the microprocessor only three wires to connect, each show has an address by the digital microprocessor write. Is to permit users to choose each BCD decoding or not decoding. Users can also choose to shutdown mode, the digital brightness control, 1 ~ 8 to choose from scanning the median and LED displays for all the test mode.

运行程序后！由于为了测试方便，AOE网初始化，所以，运行程序后，即可得到结果，结果包括拓扑排序和关键路径。-operating procedures! In order to facilitate the testing because, AOE network initialization, and operating procedures, can be obtained results include topological sorting and Critical Path.
