COLORADO SPRINGS, COLORADO -- Jeff Langr's second book, Agile Java: Crafting Code with Test-Driven Development, provides a modern introduction to professional software development. Agile Java is slated to be released by Prentice Hall PTR in February 2005, shortly after Sun's release of Java version 5.0. This code-intensive book teaches Java as a high-disciplined craft, using an object-oriented (OO) and test-driven approach from the ground up.
