The Harvester could also be called a Roomba– this robot will pick up all the beepers, ending facing West at Street7, Avenue 2.

If you have a strategy, go for it, and try it out. If you want a suggestion you can try this:

A method could pick up a row beepers, stoping when there are no others
A method that would turn North and turn toward the new row
If there are beepers to pick up, continue again, otherwise turnOff()

    {
	super(street, avenue, direction, beepers);
 
    }
 
    public void nameYourMethodHere()
    {
    	// your code here
    }
