Chapter 11, Problem 2AW
Look at the following class definitions:
class Plant:
def _ _init_ _ (self, plant_type) :
self. _ _plant_type = plant_type
def message(self):
print("I'm a plant.")
class Tree(Plant):
def _ _init_ _ (self) :
Plant. _ _init_ _ (self, 'tree')
def message(self):
print("I'm a tree.")
Given these class definitions, what will the following statements display?
p = Plant('sapling')
t = Tree()
p.message()
t.message()

Parent Class: Food
Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number).
Core Class Components
For the Food class, write:
the complete class header
the instance data variables
a constructor that sets the instance data variables based on parameters
getters and setters; use validity checking on the parameters where appropriate
a toString method that returns a text representation of a Food object that includes all three characteristics of the food
Class-Specific Method
Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage.
For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…
Child Class: Vegetable
Write a child class called Vegetable. A vegetable is described by a name, the number of grams of sugar (as a whole number), the number of grams of sodium (as a whole number), and whether or not the vegetable is a starch.
Core Class Components
For the Vegetable class, write:
the complete class header
the instance data variables
a constructor that sets the instance data variables based on parameters
getters and setters; use instance data variables where appropriate
a toString method that returns a text representation of a Vegetable object that includes all four characteristics of the vegetableJava
employee and production worker classes write an employee class that keeps data attributes for the following pieces of information: • employee name • employee number next, write a class named productionworker that is a subclass of the employee class. the productionworker class should keep data attributes for the following information: • shift number (an integer, such as 1, 2, or 3) • hourly pay rate the workday is divided into two shifts: day and night. the shift attribute will hold an integer value representing the shift that the employee works. the day shift is shift 1 and the night shift is shift 2. write the appropriate accessor and mutator methods for each class. once you have written the classes, write a program that creates an object of the productionworker class and prompts the user to enter data for each of the object’s data attributes. store the data in the object, then use the object’s accessor methods to retrieve it and display it on the screen. satak overfallow
