Numerous examples are spread throughout this book, and many of these samples include code. All pattern samples for this book can be found in the following GitHub repository: https://github.com/pragkirk/poma.
If you’re interested in running the code on your machine but are unfamiliar with Git, see the Git documentation at http://git-scm.com/documentation.
The sample code in Chapter 7 can be found in a Google Code Subversion repository at http://code.google.com/p/kcode/source/browse/#svn/trunk/billpayevolution/billpay.
I encourage everyone to download the code from these repositories and use the code while reading each pattern’s “Sample” section. Although code is included with many of the patterns, it’s not possible to include all the code for each sample. The code you find in this book helps guide you through the discussion and provides an overview of how the pattern can be applied. But, you gain far greater insight to the intricacies of the pattern by downloading and reviewing the code.
