OO Person Lab

Learning Goals

Gain proficiency instantiating a class
Gain ability to discern when to implement attr_accessor, attr_reader, and attr_writer
Gain ability to discern when to define your own attr_reader (getter) and attr_writer (setter) methods

Introduction

To practice object oriented programming (OOP), you're going to create a Person class. Each instance of the Person class will have the ability to:

Get paid/receive payments
Take a bath
Call a friend
Start a conversation
State if they are happy and/or clean

A Note on Notation

In the instructions below (and in other labs), you'll see this notation used to represent instance methods and class methods:

ClassName#method_name: represents an instance method that can be called on the class
ClassName.method_name: represents a class method that can be called on the class

For example, Person#name is an example of an instance method, that we can call on an instance of a class:

class Person
  def name
    @name
  end
end

We can also define this particular instance method using a macro (which creates the getter method for us):

class Person
  attr_reader :name

end

Person.new is an example of a class method (remember, to create a new instance of the class, we call ClassName.new, which then calls the instance method ClassName#initialize).

Instructions

Create a Person class with the behavior described below. You can use attr_ macros for some of these deliverables; for others, you'll need to write custom getter and/or setter methods.

Person.new(name): takes an argument of a name and saves it to the object. The person's name should not be able to change after initialization. When a new person is created, they should have the following attributes in addition to their name (saved to instance variables):
- @bank_account with an initial value of 25
- @happiness with an initial value of 8
- @hygiene with an initial value of 8
Person#name: gets the person's name.
Person#bank_account: gets the amount in a person's bank account.
Person#bank_account=(value): sets the value of the bank account to a new amount.
Person#happiness: gets the value of the person's happiness points.
Person#happiness=(value): sets the value of the person's happiness points. The maximum value allowed is 10, and the minimum value allowed is 0.
Person#hygiene: gets the value of the person's hygiene points.
Person#hygiene=(value): sets the value of the person's hygiene points. The maximum value allowed is 10, and the minimum value allowed is 0.
