Lab description:

Write a class named RandomWalker following the good programming practices seen in class (test, document, conventional formatting, etc). I will give you a main program that creates and manipulates RandomWalkerobjects, but it won't work correctly unless you have written RandomWalker.

A RandomWalker object should keep track of its (x, y) location. All walkers should start at the coordinates (0, 0) when created. When a walker is asked to move, it should randomly move exactly one unit either left, right, up or down (ie, adds +/- 1 to either its x or y value, but not both). Each of these four possible moves should occur with equal probability. When done repeatedly, the resulting behavior is known as a "random walk". (See an example at http://upload.wikimedia.org/wikipedia/commons/f/f3/Random_walk_2500_animated.svg)

Each RandomWalker object should have the following public methods. You may add whatever private fields or methods you feel are necessary to implement these methods:

move() : Instructs this random walker to update its coordinates by randomly making one of the 4 possible moves (up, down, left, or right).

getX() : Returns this random walker's current x-coordinate.

getY() : Returns this random walker's current y-coordinate.

getSteps() : Returns the number of steps this random walker has taken (ie, the number of time move was called).

You don't write any loops in your RandomWalker code. The program I give you will call your methods repeatedly to get its walk done.

Random walks have interesting mathematical properties. For example, given infinitely many steps, a random walker approaches 100% chance of reaching any particular (x, y) coordinate. To learn more about random walks, visit http://mathworld.wolfram.com/RandomWalk.html .

To complete the lab do the following:

Write each method.
Write brief javadoc documentation for each public method and for the class as a whole.
Write a main program in a class java that exercises all of the methods in RandomWalker and demonstrates that they are working.
Once you've done 1, 2 and 3, copy the following files into the same directory as your RandomWalker.java and run TestRandomWalker.java. You should see a random walk!
TestRandomWalker.java and Drawing Panel.java

I'll want to verify that:
~ You wrote a Main.java for testing RandomWalker.
~ Your code looks correct and well formatted.
~ You have written javadoc for all public members of RandomWalker and it compiles without warning.
~ TestRandomWalker runs correctly.
