Conclusion

This chapter covers the design process for complete systems. It focuses on combining several classes to build a system. This system is represented by UML class diagrams. The example in this chapter shows the first pass at creating a design and is not meant to be a finished design. Many iterations may be required to get the system model to the point where you are comfortable with it.

Implementing Some Blackjack Code

I recently came across a complete implementation of a blackjack game in the book Java 1.1 Developers Guide by Jamie Jaworski. If you would like to actually get your hands dirty and write some code to implement another blackjack design, you might want to pick up this good, compressive Java book.

In the next several chapters, we will explore in more detail the relationships between classes. Chapter 7, "Mastering Inheritance and Composition," covers the concepts of inheritance and composition and how they relate to each other.
