UML for Java Programmers
Robert C. Martin
All the UML Java developers need to know
You don't use UML in a vacuum: you use it to build software with a specific programming language. If that language is Java, you need UML for Java Programmers. In this book, one of the world's leading object design experts becomes your personal coach on UML 1&2 techniques and best practices for the Java environment.
Robert C. Martin illuminates every UML 1&2 feature and concept directly relevant to writing better Java software--and ignores features irrelevant to Java developers. He explains what problems UML can and can't solve, how Java and UML map to each other, and exactly how and when to apply those mappings.
