A5 Introduction page 1 of 11

This lesson discusses how to design your own classes. This can be the most challenging part of programming. A truly good design can be the difference between hundreds of hours working with complex code and two hours working in an elegant system. A well thought out design can make the programming portion far easier. In fact, for many professional projects, more time is spent designing programs than actually typing in code. Imagine a million lines of code in a project with a design flaw. Redesigning that much code could be horrendous!

The key topics for this lesson are:

  1. Designing a Class
  2. Determining Object Behavior
  3. Instance Variables
  4. Implementing Methods
  5. Constructors
  6. Using Classes
