Exploring Kotlin with Ken Kousen
March 20, 2019
Kotlin is an exciting new language for the JVM from the folks at Jetbrains. Kotlin has been making waves for a couple years now in the Android space but, as a general purpose language, it is finding it's way into many projects and developers seem to love it!
For those of us who haven't been hands-on yet, Ken gives us an overview of the language, it's features, and why it's worth getting excited about!

This week I gather around the microphone with Ken Kousen where he reflects on a life and career focused on the JVM.
What's new in Groovy, Grails & the G3 summit
October 19, 2016
This week I sit down with Ken Kousen (Kousen IT, Groovy Podcast) and Jeff Brown (OCI) and we talk about what's new in the world of Groovy, Grails as well as their plans for the upcoming (G3 Summit).
Exploring Groovy, Grails3 and more with Ken Kousen
January 11, 2016
We're joined with Ken Kousen to discuss the current state of Groovy, Grails3 and why those technologies are well worth exploring.
The time for Groovy is now. It makes your life easier and quicker. Anything you do in Java you can simplify by a good factor of five-maybe 10-and still have code that's easy to write, easy to follow and easy to maintain.
The introduction of functional programming concepts in Java SE 8 was a drastic change for this venerable object-oriented language. Lambda expressions, method references, and streams fundamentally changed the idioms of the language, and many developers have been trying to catch up ever since. This cookbook will help. With more than 70 detailed recipes, author Ken Kousen shows you how to use the newest features of Java to solve a wide range of problems.
For developers comfortable with previous Java versions, this guide covers nearly all of Java SE 8, and includes a chapter focused on changes coming in Java 9. Need to understand how functional idioms will change the way you write code? This cookbook—chock full of use cases—is for you.
Using the Android Studio IDE and the Gradle build tool will make Android app development much simpler—as long as you know your way around Gradle. This practical guide shows you how Gradle works with Android so that you can use it effectively on your projects. You’ll learn ways to customize project layouts, add dependencies, and even generate multiple different versions of your application.
Making Java Groovy is a practical handbook for developers who want to blend Groovy into their day-to-day work with Java. It starts by introducing the key differences between Java and Groovy—and how you can use them to your advantage. Then, it guides you step-by-step through realistic development challenges, from web applications to web services to desktop applications, and shows how Groovy makes them easier to put into production.
About this Book
You don't need the full force of Java when you're writing a build script, a simple system utility, or a lightweight web app—but that's where Groovy shines brightest. This elegant JVM-based dynamic language extends and simplifies Java so you can concentrate on the task at hand instead of managing minute details and unnecessary complexity.
Making Java Groov is a practical guide for developers who want to benefit from Groovy in their work with Java. It starts by introducing the key differences between Java and Groovy and how to use them to your advantage. Then, you'll focus on the situations you face every day, like consuming and creating RESTful web services, working with databases, and using the Spring framework. You'll also explore the great Groovy tools for build processes, testing, and deployment and learn how to write Groovy-based domain-specific languages that simplify Java development.
Written for developers familiar with Java. No Groovy experience required.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
