QUESTION: I am very confused on how to start programing for this.....I am having trouble setting up how the bear would rotate and how i would monitor the steps...YOU DONT HAVE TO WRITE THE WHOLE PROGRAM I JUST NEED SOMEWHERE TO START PLEASE!

Our bear lives in a two-dimensional (x-y) coordinate system and should be able to rotate left, rotate right and step. When it steps, it will move one whole unit in the direction it is facing.

Create a UML class diagram for your bear. It should have three behaviors: rotate left, rotate right and step. Your bear will also need some attributes, namely its x-y location and a heading.

Implement your Bear class in Java, saving it in file Bear_pt1. Do not include a main method in your Bear.

Implement a main class to test your Bear. Test your Bear by giving it a series of step/rotate commands and then print its final position. Note that your Bear

Explanation / Answer

public class Bear
{
   int x,y;
   char faceDirection; //it can be N,w,E,S
   public Bear() //By default
   {
       x = 0;
       y = 0;
       faceDirection = 'E';
   }
   //this method will change the direction of Bear. If bear is facing North, then rotate left will make it direction as West.
   public rotateLeft()
   {
       if(faceDirection == 'N')
           faceDirection = 'W';
       else if(faceDirection == 'W')
           faceDirection = 'S';
       else if(faceDirection == 'E')
           faceDirection = 'N';
       else if(faceDirection == 'S')
           faceDirection = 'E';
   }
   public rotateRight()
   {
       if(faceDirection == 'N')
           faceDirection = 'E';
       else if(faceDirection == 'W')
           faceDirection = 'N';
       else if(faceDirection == 'E')
           faceDirection = 'S';
       else if(faceDirection == 'S')
           faceDirection = 'W';
   }
   //increase 1 unit in the direction it is facing.
   public step()
   {
       if(faceDirection == 'N')
           y = y + 1;
       else if(faceDirection == 'W')
           x = x - 1;
       else if(faceDirection == 'E')
           x = x + 1;
       else if(faceDirection == 'S')
           y = y - 1;
   }
   public getLocation()
   {  
       System.out.println("("x+","+y+") facing "+faceDirection);      
   }

}
