This book introduces all the major aspects of Groovy development and emphasizes Groovy's potential as a learning tool. Case studies and exercises are included, along with numerous programming examples. The book begins assuming only a general familiarity with Java programming, and progresses to discuss advanced topics such as GUI builders, Groovlets, Unit Testing, and Groovy SQL.
Key Features
- The first comprehensive book on Groovy programming that shows how writing applications and scripts for the Java platform is fast and easy
- Written by leading software engineers and acclaimed computing instructors
- Offers numerous programming examples, code samples, detailed case studies, exercises for self-study, and a companion website with a Windows-based Groovy editor
