Dragonfly

("Critter" classes come from Marty Stepp's "Critters" homework assignment. See "Critters spec" link above for more information.)

Write a class Dragonfly that extends the Critter class from the Critters assignment. Whenever a Dragonfly encounters food, it eats it. Eating affects the Dragonfly's movement.

Dragonfly objects move in a N/E/S/E sequence, initially going east once between going north and south, but going east an additional time for each time the Dragonfly has eaten.

  • If the Dragonfly has never eaten: North, East, South, East, and repeat
  • If the Dragonfly has eaten once: North, East, East, South, East, East, and repeat.
  • If the Dragonfly has eaten twice: North, East, East, East, South, East, East, East, and repeat.
  • ...

We will be somewhat flexible about what should happen if a Dragonfly eats in the middle of a movement sequence. Either it should take effect immediately, lengthening the rest of that sequence and all subsequent ones; or it can take effect at the beginning of the next overall N/E/S/E movement sequence, lengthening it and all subsequent sequences.

You may add anything needed (fields, constructors, etc.) to implement this behavior appropriately.
