putPeeper() 等方法, 并在Main中调用显示相关信息; 4. 给类和各方法添加注释, 并使用javadoc指令输出代码文档. (现新建doc文件夹在D:\\下以存储文档，控制台输入：javadoc -d D:\\doc ) homework02 2011-02-27 22:32 修路工: 请使用分附件中的空白项目，装载sample03_holes_ 背景，修缮1st Street。/* * File: * -------------------------- * The SampleKarel subclass as it appears here does nothing. */ import *; /* * Name: * Section Leader: */ public class SampleKarel extends SuperKarel {int count = 0; public void run() { // You fill in this part while(count } if (frontIsBlocked() || rightIsClear()) { changeDirection(); } move(); public void changeDirection() {if (rightIsClear())
