1. Create an enumerated data type Color for the possible flower colors for a plant (red, purple,
white, none) Create an abstract class Plant with the following features: • class variable
ENERGY_SOURCE whose value is “carbon dioxide” • instance variables for color and watering
• no-argument constructor that sets flower color to white • constructor that takes user-specified
color (both constructors should set watering by calling getRandomWatering()) • getter • setter •
toString() • abstract method getRandomWatering() that returns int for days between watering
Create a Fern class that extends Plant and contains the following: • no-argument constructor that
assigns color value of none (ferns don’t have flowers) • method getRandomWatering() that
returns 7 three out of five times, 10 the rest • toString() Create a Succulent class that extends
Plant and implements Comparable and contains the following: • class variable called
numberOfSucculents to count succulent objects • class method numberOfSucculents() that
returns number of succulents • instance variable hasSpines that is set to true if plant is a cactus,
false otherwise • no-argument constructor that assigns default value of false for hasSpines and
white for color • constructor that assigns user-specified values for hasSpines and color • copy
constructor • getter (call it hasSpines rather than getSpines since it returns a boolean) • setter •
toString() • method getType() that returns “cactus” if hasSpines is true, “succulent” otherwise •
method isSameType() that returns true if both plants are the same subtype • method
getRandomWatering() that returns a random value between 14 and 28 • method compareTo()
that returns 1 if first plant can go more days between waterings, 0 if both same, -1 if first can go
fewer days
