Drunkard.java Your Drunkard class. The interface is provided. You will be completing the implementation, and a test driver for it.

RandomWalkViewer.java Your RandomWalkViewer class. You create this file and class.

RandomWalkComponent.java Your RandomWalkComponent class. You create this file and class.

DrunkardTester.java Your unit test program for your Drunkard class. You create this file and class.

ImPoint.java An immutable point class for use in this program. Do not modify or submit this file.

ImPointTester.java Unit test program for ImPoint. Use this to test out ImPoint. Also can be used as an example of what a test program might look like. Do not submit this file.-In this assignment you will write a graphics-based program to do a random walk, sometimes also known as a drunkard s walk. This random walk simulates the wandering of an intoxicated person on a square street grid. The drunkard will start out in the middle of the grid and will randomly pick one of the four compass directions, and take a step in that direction, then another step　that new location in a random direction, etc. This will be repeated some number of times determined by the user. The output will display the path of the drunkard as a sequence of line-segments. (This problem is adapted　programming problem P6.6　the textbook.)



This assignment will give you practice with creating classes, using loops, using the java library for random number generation, doing console-based IO, and drawing to a graphics window. Also you ll get practice in general program development.
