This archive contains all the code examples found in Functional Programming for Java Developers, with the exception of several code snippets in the text.
All the source files are in the src directory and the corresponding JUnit tests are in the test directory. There is also a lib directory that includes several third-party libraries used for testing or as part of some of the examples. These libraries are subject to their individual license restrictions.
junit-4.5.jarfor unit tests (web site, license).- The Akka framework for the Actor and STM examples (web site, license).
- The Multiverse library, which is used by Akka for STM (web site, license).
- The Scala language runtime library, which is used by Akka (web site, license).
You'll notice that some of the src files have the extension .javax. These files do not compile with javac, either because they include hypothetical extensions to Java, as discussed in the book, or they assume the existence of libraries that don't actually exist, such as an updated, "functional" version of the AWT.
You can load this directory as an Eclipse project. The required .project and .classpath files are included in this directory.
While Java projects are typically built with ant or maven, I just used Gnu Make, with a conventional Makefile. This is the version of make on all Linux, MacOS X, and Cygwin systems.
To build and run the examples, all you need is a recent of version of the Java SDK installed and set up on your system PATH. Required third-party libraries are in the lib directory.
To build the examples and run the tests, open a terminal window and change to the code-examples directory. Then run the make command. This builds the default all target, which depends the compile and tests targets. You'll see output for the test runs, ending in OK if they were successful.
I welcome feedback on the examples (and the book for that matter). You can post comments, corrections, etc. on the O'Reilly forum. The book's web site will provide access to the forum, too: http://oreilly.com/catalog/9781449311032/.
