The JCG book specifically targets the Java platform. All the same, there's plenty of advice that carries forward to Groovy and Java-like languages. Groovy may require an additional set of best practices, but after reading this book it will be intuitive to apply the suggested concepts / recommendations to the programming language of your choice.
