CIS 3931 - Elementary Java Programming

A Few More Class Examples (from Chapter 9)

• A class example representing rational numbers (fractions)
  • Rational.java - the class Rational.
  • TestRationalClass.java - a sample test program illustrating use of Rational objects
• Some classes that illustrate composition of objects
  • Name.java - class Name, first seen in chapter 8
  • Address.java - a class for creating objects that store addresses
  • Person.java - a class that has an Address object and a Name object as instance variables. This is an example that uses composition (the "has-a" relationship), since every Person object has a Name object and an Address object embedded as components.
