Graphical Random Walker

Using the Walker class developed earlier, we can graphically follow a random walker as she moves through a “world” laid out on the computer screen.

Assume the screen is 120 blocks (characters) wide, and 25 blocks tall. The walker starts at the center of the screen and moves randomly from there. After each move:

• clear the screen (requires running in a Terminal)
• use nested loops to print every row, every column of the world, with:
• a “ ” meaning nothing is there
• a “+” at the origin of the walker
• a “@” where the walker is currently located
• below the world print the number of steps taken and the coordinates of the current location

Write a GraphicalRandomWalker program that uses the Walker class to implement this simulation.
