Question

Answer the prompt with given main method:

Code:

import java.awt.*;

public class TestRandomWalker {

public static final int STEPS = 500;

public static void main(String[] args) {

RandomWalker walker = new RandomWalker(); // instantiate Walker object

DrawingPanel panel = new DrawingPanel(500, 500);

Graphics g = panel.getGraphics();

// advanced features -- center and zoom in the image

panel.getGraphics().translate(250, 250);

panel.getGraphics().scale(4, 4);

// make the walker walk, and draw its movement

int prevX = walker.getX(); // initialize Walker display

int prevY = walker.getY();

for (int i = 1; i <= STEPS; i++) {

g.setColor(Color.BLACK);

g.drawLine(prevX, prevY, walker.getX(), walker.getY()); // update Walker display

walker.move(); // move Walker 1 step

prevX = walker.getX(); // update x value

prevY = walker.getY(); // update y value

g.setColor(Color.RED);

g.drawLine(prevX, prevY, walker.getX(), walker.getY()); // update Walker display

int steps = walker.getSteps(); // record Walker steps

if (steps % 10 == 0) {

System.out.println(steps + " steps");

}

panel.sleep(100);

}

1. Define a class named Randomwalker. A Randomwalker object should keep track of its (x, y) location. All
walkers start at the coordinates (0, 0). When a walker is asked to move, it randomly moves either left, right,
up or down. Each of these four moves should occur with equal probability. The resulting behavior is
known as a "random walk." (A 2-dimensional random walk example is pictured at right.)
Each Randomwal ker object should have the following public methods. You may add whatever fields or
methods you feel are necessary to implement these methods:
move ()
Instructs this random walker to randomly make 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.
getsters ()
Returns the number of steps this random walker has taken.
