Question

Critters move around in a world of finite size, but the word is toroidal (going off the end to the right brings you back to the left and vice versa; going off the end to the top brings you back to the bottom and vice versa).

You are allowed to include a constructor for your classes if you want, although it must be a zero-argument constructors (one that takes no arguments).

You are to implement five classes. The behavior of each class is described below.

Class

getChar

getMove

Bird

B

Randomly selects one of the four directions each time

Frog

F

Picks a random direction, moves 3 in that direction, repeat (same as bird, but staying in a single direction longer)

Mouse

M

West 1, north 1, repeat (zig zag to the NW)

Turtle

T

South 5, west 5, north 5, east 5, repeat (clockwise box)
