3.0 étoiles sur 5 Would have been better if mentioned what is not covered in case it was of interest to the reader 7 décembre 2011

This book is a good idea as a quick survey of new features in Java 7, but it is missing a crucial piece. I don't mind that the author did not cover all features in in the survey, but it would have been useful for me see a complete list of other enhancements that were included in Java 7. This way I would know if I was interested in finding more details on something else. I looked up the release notes on the Oracle web site and including an index below in case someone will find that information useful for reference as well. For example, I have to deal with the mixed environment which has Java and non-Java languages, and there are enhancements in that area that are potentially critical for my needs: the Garbage-First Collector and JVM support for non-Java languages. I would have liked to see all areas mentioned, even if there were no additional details.

The areas the author covers are easy to understand and give you just enough details to know if these features are going to be useful/relevant.

From Oracle release notes, the following areas have enhancements in Java 7:
* Swing
* IO and New IO
* Networking
* Security
* Concurrency Utilities
* Rich Internet Applications (RIA)/Deployment
o Requesting and Customizing Applet Decoration in Dragg able Applets
o Embedding JNLP File in Applet Tag
o Deploying without Codebase
o Handling Applet Initialization Status with Event Handlers
* Java 2D
* Java XML - JAXP, JAXB, and JAX-WS
* Internationalization
* java.lang Package
o Multithreaded Custom Class Loaders in Java SE 7
* Java Programming Language
o Binary Literals
o Strings in switch Statements
o The try-with-resources Statement
o Catching Multiple Exception Types and Rethrowing Exceptions with Improved Type Checking
o Underscores in Numeric Literals
o Type Inference for Generic Instance Creation
o Improved Compiler Warnings and Errors When Using Non-Reifiable Formal Parameters with Varargs Methods
* Java Virtual Machine (JVM)
o Java Virtual Machine Support for Non-Java Languages
o Garbage-First Collector
o Java HotSpot Virtual Machine Performance Enhancements

And here is the index from "What's new in Java 7" by Madbusudban Konda.

Language Enhancements
Diamond operator
Using Strings in switch statements
Automated resource management
Numeric Literals with underscores
Improved exception handling
New file system API (NIO 2.0)
Working with Path
File change notifications
Fork and Join
Supporting Dynamism

The author may very well be an experienced Java programmer. That being the case, the only justification for the typos in this very slight intro to Java 7 is that he just threw it together without paying much attention or running the code.

An obvious example is his brief explanation of the new Path class. He suggests that if one uses:
Path path = Paths.get("c:\\Temp\\temp");

will return "temp.txt" which just isn't the case, it will return "temp" regardless (on Windows anyway) of whether or not there is a file that starts with that name or a folder that has that name or if there is nothing for the lowest level at all.

I've given this thing two stars rather than 1 because it isn't completely useless: If you want a brief (took me 10 minutes to glance through it) idea of what's new in 7, it works. Just don't look for anyting but the concepts. Almost any of the online intros to 7 would be better.

This book should be deleted from Amazon. What a shame. The book is not even complete as most of the online reviews of Java 7 you can find using google

This 'book' is an incomplete list of Java 7 features. I would recommend getting this information directly from the 'horses mouth' instead [...]
3.0 étoiles sur 5 Nice try, but lacking 24 novembre 2012

I like the concept of this book -- a short book of just what's different about the latest version of XYZ -- and think publishers should do more of that. I'm tired of buying $50 technical books to see what turns about to be 20 pages of new stuff and 200 pages of rehash.

So this 'book' gets a few stars from me for that. Where it falls short is that it's not complete and doesn't really say that, and it's ultimately an ad for other books. So if feels like a rip-off. It's free, so it's not a financial rip-off, but it took my time and attention and left me with what I think is the incorrect impression that there's not a lot new in Java 7.

I do think there's a market for pamphlet-sized books that sell for only a few bucks that assume you have knowledge of a product and just need to know what's new. This one isn't it.
