Basic Requirements
Write a super basic Pizza ordering system using Polymorphism.
LiFiUnit5Ch14 (driver)
• Get input for Cheese or Meat pizza.
18%
• Declare a single pizza of LiFiPizza type to be used for both Cheese and Meat
• If a Meat pizza is selected
o instantiate your pizza as a LiFiMeat pizza with zero arguments
o call setCrust() of LiFiMeat
o call setIngredient of LiFiMeat
• If a Cheese pizza is selected,
o Instantiate your pizza as a LiFiCheese pizza with zero arguments.
• Print your order by printing the pizza object (should call the corresponding
toString() method implicitly)
LiFiPizza.java
• abstract class
• private instance data members: type (String), crust(String), and cost (double)
• Default constructor: set cost to initial value $5
• Accessor (getXXX) and mutator (setXXX) methods for each instance data
member
26%
LiFiCheese.java (extends LiFiPizza)
• Default constructor: call appropriate mutator methods of parent class to set
type to “Cheese” and set crust to “Thin”
• Override toString() to return a String representing the state of the Cheese
pizza object. See the sample for the format of the data
16%
LiFiMeat.java (extends LiFiPizza)
• private instance data member: ingredient (String)
• Default constructor: call appropriate mutator method of parent class to set type
to “Meat”
• setCrust(): this method is an overloaded version of the setCrust(String) of
parent class. Allow selection of Thin or Thick crust and call setCrust(String) of
parent class to set instance data member crust (see Sample)
• setIngredient():
o prompt for and input one ingredient (can be any ingredient, but just
one. see Sample)
o add $2 to the initial cost
• Override toString() to return a String representing the state of the calling Meat
pizza object. See the sample for the format of the data
