stanford JAVA公开课使用的Karel机器人空白工程 ，亲测可以用

/* * File: BlankKarel.java * --------------------- * This is a blank Karel project that you can change at will. Remember, if you change * the class name, you'll need to change the filename so that it matches. * If you want to make the program load with a specific world, make the * world file named the same as this class. For example, when this program is * run, it would try to load BlankKarel.w if there is one. */ import acm.program.*; import stanford.karel.*; public class BlankKarel extends Karel { public void run() { /* You fill this in */ } }
