代码说明：

实现9层电梯控制 功能如下：1，先假设没上楼之前，楼层运行看不到(没图形），可以当做随机看待。 2。当在某层按电梯开关后，在屏幕显示电梯停到该指定楼层的图形状态。 3。随后可以按想去的楼层，在屏幕显示电梯运动过程，， 4，可选择是否还执行本程序（坐电梯）-9 realize elevator control layer functions as follows: 1, first assume that no public housing, before running the floor can not see (no graphics) can be viewed as random. 2. When a layer switch by the elevator, the elevator stopped on the screen display to the graphics state designated floors. 3. Then may want to go to the floor, in the screen display elevator movement process, 4, can choose whether the implementation of this program (elevator)
