Functionality

The application App creates a Model object
The Model class
- creates 3 Student objects
- displays information about the three students
- compares the birth dates of the three Student objects
- displays a message stating who is the oldest

The classes

App
- it has the main method which is the method that Java looks for and runs to start any application
- it creates an object (an instance) of the Model class
Model
- this is the class where all the action is going to happen
- it creates three students and compare their birth dates and displays a message stating who is older or if they are of the same age
- make sure you test your application for all the possible cases
Student
- has the following attributes
  - int studentId;
  - String firstName;
  - String lastName;
  - BirthDate birthday;
  - Address address;
  - String phoneNumber;
BirthDate
- it is a class (or type) which is used in Student defining the type of the attribute birthday
- it has three attributes
  - int month;
  - int day;
  - int year;
- it also has a method that returns a formatted string with month, day, year:
  - for instance: 10/10/2000
Address
- it is a class (or type) which is used in Student defining the type of the attribute address
- it has the following attributes:
  - String addressLine1
  - String addressLine2
  - String city
  - String state
  - int zipCode
- it also has a method that returns a formatted string such as (without the bullets):
  - 25 Yearsley Mill Rd
  - Media, PA 19063

Don't use static variables and methods
• Encapsulation: make sure you protect your class variables and provide access to them through get and set methods
• all the classes are required to have a constructor that receives all the attributes as parameters and updates the
attributes accordingly
• all the classes are required to have an "empty" constructor that receives no parameters but updates all the attributes
as needed
• Follow Horstmann's Java Language Coding Guidelines
• Organized in packages (MVC - Model - View Controller)
