Hello Authors ,

I have two quick questions after seeing the summary of the book..

1. What might be the purpose of including JVM-based languages Groovy, Scala, and Clojure in the book.

2. It's noted modern approaches to testing, build, and CI are discussed. Does testing denotes JUnit testing and build discusses regarding build tools like Ant?

Thank you!

Several otehr rcent threads have covered this but in short: The Well-Grounded Java Developer is actually a Well-Grounded JVM Language Developer, using the right language for the right problem domain. For example Clojure and Scala have more inbuilt support for concurrency, Groovy/Grails is very strong for rapid web development etc. Java the language isn't the Golden Hammer for everything but you can mix and match languages in your project as they all run on the JVM!

It does discuss some JUnit testing, but more about the TDD approach (using JUnit as the testing framework). It discusses Maven over Ant (but covers why Ant is no longer as popular as it once was).

Hope that helps!
