[求助]
请大神帮看下我这个代码有什么问题，运行的时候换一个地图就不行了，，，，
|
|
这是网易公开课中《编程方法学》其中一项作业，让Karel找到地图中点并放下一个方块，我写的代码换一个地图就不起作用了 本人Java小白，自学中，请各位虫友帮忙找下漏洞，，， /* * File: MidpointFindingKarel.java * ------------------------------- * When you finish writing it, the MidpointFindingKarel class should * leave a beeper on the corner closest to the center of 1st Street * (or either of the two central corners if 1st Street has an even * number of corners). Karel can put down additional beepers as it * looks for the midpoint, but must pick them up again before it * stops. The world may be of any size, but you are allowed to * assume that it is at least as tall as it is wide. */ import stanford.karel.*; public class MidpointFindingKarel extends SuperKarel { int i=1; public void run() { countWid(); turnAround(); moveToMid(); putBeeper(); } private void countWid() { while (frontIsClear()) { move(); i=i+1; } } private void moveToMid() { double x=i/2.0; if (i%2==0) { for (int j=1;j<x;j++) { move(); } putBeeper(); move(); } else { for (int j=1; j<x;j++) { move(); } } } }  初始界面.png  换一个地图后.png  运行程序后.png |
