Key benefits

Simple and more advanced recipes to cover a broad number of topics and challenges

With scores of practical examples, this book will help you to build efficient, flexible, and well-integrated systems

Solve everyday programming problems with the elegance and simplicity of Groovy 2

Description

Get up to speed with Groovy, a language for the Java Virtual Machine (JVM) that integrates features of both object-oriented and functional programming. This book will show you the powerful features of Groovy 2 applied to real-world scenarios and how the dynamic nature of the language makes it very simple to tackle problems that would otherwise require hours or days of research and implementation. Groovy 2 Cookbook contains a vast number of recipes covering many facets of today's programming landscape. From language-specific topics such as closures and metaprogramming, to more advanced applications of Groovy flexibility such as DSL and testing techniques, this book gives you quick solutions to everyday problems. The recipes in this book start from the basics of installing Groovy and running your first scripts and continue with progressively more advanced examples that will help you to take advantage of the language's amazing features. Packed with hundreds of tried-and-true Groovy recipes, Groovy 2 Cookbook includes code segments covering many specialized APIs to work with files and collections, manipulate XML, work with REST services and JSON, create asynchronous tasks, and more. But Groovy does more than just ease traditional Java development: it brings modern programming features to the Java platform like closures, duck-typing, and metaprogramming. In this new book, you'll find code examples that you can use in your projects right away along with a discussion about how and why the solution works. Focusing on what's useful and tricky, Groovy 2 Cookbook offers a wealth of useful code for all Java and Groovy programmers, not just advanced practitioners.

Who is this book for?

This book is for Java developers who have an interest in discovering new ways to quickly get the job done using a new language that shares many similarities with Java. The book's recipes start simple, therefore no previous Groovy experience is required to understand the code and the explanations accompanying the examples.

If you have any feedback about the product you're reading, or Early Access in general, then please fill out a contact form here and we'll make sure the feedback gets to the right team.

Can I download the code files for Early Access titles?

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date?

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready?

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter. The new chapters are automatically added to your account, so you can also check back there any time you're ready and download or read them online.

I haven't read any of the other Groovy/Grails cook or recipe books but I was impressed by this one. Compared to the Intro books that I've read, it is much quicker to come up to speed on topics quickly. The book is almost 400 pages but you don't feel like you need to get to 400 to be able to do anything interesting (and let's face it, by the time you reach page 400 you've already forgotten the first 200).It is well organized and well edited covering a wide range of topics that you might not find elsewhere. For example, I liked the discussion of integration with a few of the build tools (Gradle, Ant, Maven, etc) and the commentary that comes along with them. I'm not a professional Java developer and while I've heard of these tools they're use in practice has always been pretty vague to me. Books like these are good for learning the patterns that professional developers pick up in practice on a day to day basis. What the authors choose to include is useful in addition to what they have to say on the topics for example.

The authors are clearly seasoned IT professionals, they teach you the most advanced features of Groovy with great competence and neatness. Particularly appreciated the chapter on the DSL, on AST and dynamic behavior definition. The examples are clear and terse, and the book can be read front to cover without being boring at any time. I have gained more knowledge from this book than from any other book on Groovy I have read before (Groovy for DSL, Groovy in Action)

This is a really good introduction to Groovy. Was able to start this on a flight from Orange County to Seattle, and by the time I arrived I was already productive thanks to the good coverage of the basics early on, and the cookbook examples which cover many scenarios from JSON processing, web requests and more.The best thing about this format was, I could skip chapters for topics that weren't immediately relevant. Kudos to the authors for making that possible.There were several typos, which was a little jarring, but it was always pretty obvious what the authors meant.

First of all, where I come from: I've been using Groovy in Grails web applications for some years. Once in a while I create a Groovy script to work out things, like how much rice the king's chessboard contained. So, I'm not a total Groovy newbie, but I only use the subset of Groovy needed for Grails.The title says "cookbook", but this book goes beyond that. It explains Groovy principles in greater depth than I expected a cookbook would do, but not in the same depth as, for example Groovy in Action, Second Edition, which is also close to 400 pages longer. This means it's accessible to Groovy users with only a small to moderate knowledge of Groovy. One does not expect a cookbook to cover all the intricacies of the subject it deals with and can't fault a cookbook style book for this. The page count also comes in at under 400, that's including an index which looks quite detailed. This is a nice length.Like one reviewer said, this book also shows one how to use libraries which are available to do many very useful things. Personally I didn't know of most of these libraries. This, alone, goes a long way in making this book worthwhile.The language is clear, simple and straightforward. Nobody will have any problems there.The recipes, which is what a cookbook is all about, are more or less useful, depending on what one wants and needs. How they work is explained in detail after each recipe. Of course, it's not to say that if one has no use for something now, one won't have any use for it in the future.My advice is to read it in some e-book reader and put in bookmarks as you go. I'm going to go through it again using Calibre. You will definitely come back to it from time to time.The probability that anyone programming in Groovy will be very happy with this book is very high.

I found this book an excellent resource for my work writing groovy scripts. I deal with legacy code and data sources in my job capacity and am constantly updating Groovy, Java and PL/SQL scripts to make them more efficient and maintainable. This book offers plenty of examples of common on-the-job scenarios where Groovy would be appropriate.The book has many examples with Groovy as a standalone language. There are a few examples of using Groovy and common ecosystem frameworks/ tools but they are very basic and deal largely with set up. If you are looking for a book that will give you examples of how to use Groovy in a framework like Grails, be aware the scope of the book does not cover Grails and Groovy.I use this book as a quick reference guide for on the job scripting. Its examples provide a solid starting point for many common tasks and also help with Groovy version migration. I would recommend this book to any person who deals with Groovy on a regular basis as it will help you learn to make your code more Groovy while leaving it maintainable.

Groovy 2 Cookbook: Java and Groovy go together like ham and eggs, and this book is a great opportunity to learn how to exploit Groovy 2 to the full. Packed with recipes, both intermediate and advanced, it's a great way to speed up and modernize your programming.
