Summary 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 ...
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 coo...

Use Kotlin to build Android apps, web applications, and more—while you learn the nuances of this popular language. With this unique cookbook, developers will learn how to apply thisJava-based language to their own projects. Both experienced programmers and those new to Kotlin will benefit from the practical recipes in this book. Author Ken Kousen (Modern Java Recipes) shows you how to solve problems with Kotlin by concentrating on your own use cases rather than on basic syntax. You provide the contextand this book supplies the answers. Already big in Android development, Kotlin can be used anywhere Java is applied, as well as for iOS development, native applications, JavaScriptgeneration, and more. Jump in and build meaningful projects with Kotlin today. Apply functional programming concepts, including lambdas, sequences, and concurrency See how to use delegates, late initialization, and scope functions Explore Java interoperability and access Java libraries using Kotlin Add your own extension functions Use helpful libraries such as JUnit 5 Get practical advice for working with specific frameworks, like Android and Spring
Android adopted Gradle as the preferred build automation system a few years ago, but many Android developers are still unfamiliar with this open source tool. This hands-on guide provides a collection of Gradle recipes to help you quickly and easily accomplish the most common build tasks for your Android apps. You’ll learn how to customize project layouts, add dependencies, and generate many different versions of your app. Gradle is based on Groovy, yet very little knowledge of the JVM language is required for you to get started. Code examples use Android SDK version 23, with emulators from Marshmallow (Android 6) or Lollipop (Android 5). If you’re comfortable with Java and Android, you’re ready. Understand Gradle’s generated build files for Android apps Run Gradle from the command line or inside Android Studio Add more Java libraries to your Android app Import and export Eclipse ADT projects Digitally sign a Release APK for the Google Play store Use product flavors to build many versions of the same app Add custom tasks to the Gradle build process Test both your app’s Android and non-Android components Improve the performance of your Gradle build
Big Java: Early Objects, 7e focuses on the essentials of effective learning and is suitable for a two-semester introduction to programming sequence. The text requires no prior programming experience and only a modest amount of high school algebra. Objects and classes from the standard library are used where appropriate in early sections with coverage on object oriented design starting in Chapter 8. This gradual approach allows students to use objects throughout their study of the core algorithmic topics, without teaching bad habits that must be un-learned later. The second half covers algorithms and data structures at a level suitable for beginning students.
With this book readers can become real geographic programmers using the Java programming language. They will find working code examples in Java using some of the many GIS-oriented applications and APIs, and be able to display GIS data on the Web, manipulate GIS data, and programmatically store and retrieve it in geographically enabled databases.
Summary Groovy in Action, Second Edition is a thoroughly revised, comprehensive guide to Groovy programming.
