Modern Java: Java 7 and Polyglot Programming on the JVM Paperback – 2 Feb. 2014

It is a short book but gives a good overview of both Java (pre 8 but with some discussion) and tools/eco-system. Worthwhile because it is an easy read and can be covered in a weekend including exploring some of the concepts/tools, it is however quite broad and not huge detail but it does cover wide and I appreciate that.If there is a takeaway it is most books never get read fully, not only will you read this completely but it will refresh your knowledge of the ecosystem and perhaps give you new areas to explore.Probably best for the experienced Java professional who would like to look further than the language itself.Recommended.
