Exercise : Hyena

Write a class Hyena that extends the Critter class, along with its movement behavior. All unspecified aspects of Hyena use the default behavior.

A Hyena object moves in a rectangular pattern looking for food, walking NORTH, then EAST, then SOUTH, then WEST. Each time the hyena walks an entire rectangle, it starts the rectangle pattern over again but with a rectangle 1 step wider than before. The general pattern is as follows:

• N, E, S, W, N, E, E, S, W, W, N, E, E, E, S, W, W, W, N, E, E, E, E, S, W, W, W, W, ...

Solve this program in jGRASP using the CritterMain simulator.
