 Make a Maze with 4 to 6 walls and one beeper.  Place the Robot in the start position, and the beeper in the end position.
-You can post your .java file in GoogleClassroom..  If you want you can post it with or without the task that is the solution to your maze.
+You can post your .java file in GoogleClassroom.
 Make your plan and exchange it with another student.  He has to make a task to run your maze, and you have to make a task to run his.  Help one another.  Start with a simplified task that turns off right after the robot is made.  After the maze is correct, you can finish the task by adding the ''move()'' and ''turnLeft()'' methods for the robot to run the maze.

 ====== 3 Ways to Make Walls ======
   - World.placeNSWall(), World.placeEWWall() have three parameters (sometimes called arguments).  You need to tell these methods three integers,  For a East-West Street: the number of the street, the number of the Avenue, and the length of the wall (either going East or North, depending on the direction. Once you get the hang of reading the [[http://csis.pace.edu/%7Ebergin/KarelJava2ed/KJRdocs/kareltherobot/World.html|API]] of a class you can quickly use or build upon other people's code (or even your own). <code java>import kareltherobot.*;
