~Problem 4.1~

You will apply the concepts you have learned in this lab. Your task will be to develop two new classes (Person and InfectedPerson), which will interact with the Corona class you completed from before.

Notes:

• You are not allowed to modify Virus.java.
• You will need your completed solution for the Corona class from 2.3.
• Where you are unsure, use your judgment or make an assumption.
• All your classes require complete Javadoc document comments.

Person:

• Person should have fields for: name, age (Integer).
• There should be accessor and setter methods for all the above fields.
• Person has two constructors:
  1. A default constructor which initializes the respective fields to "", 0.
  2. An overloaded constructor which takes both fields as parameters and initializes accordingly.

InfectedPerson:

• InfectedPerson is a subclass of Person.
• InfectedPerson should have fields for: underlyingConditions, symptoms (both ArrayLists), and diagnosis (of type Corona).
• InfectedPerson should have two constructors:
  1. A constructor that takes as parameters all the fields specific to InfectedPerson except diagnosis. diagnosis should always be initialized to null.
  2. A second constructor that takes as parameters all the fields specific to InfectedPerson (except diagnosis), + name and age.
  Remember your calls to super(), there should never be an uninitialized field!
• InfectedPerson needs accessor methods for all its fields.
• InfectedPerson needs mutator methods for underlyingConditions, symptoms. These methods should take String parameters and add the supplied values to the respective ArrayList. You MUST check for duplicates before adding!

• InfectedPerson has a method called isSymptomatic(). This method takes a Corona object as a parameter. An InfectedPerson is said to be symptomatic if they have at least 75% of the symptoms from the Corona object's symptoms field. If the InfectedPerson does have at least 75% of the symptoms the diagnosis is set to the Corona object, and a boolean true is returned. Otherwise, just return false.
