Java SE Webinar Replay

Learn how improvements to the Java platform, APIs and the Java language will help you develop innovative applications using parallel programming, integration with other languages and tools, and APIs that will substantially boost your productivity. Watch three webinar sessions from the April edition of Virtual Technology Summit

Java on Mobile: Johan Vos shows how easy it is to create a highly-polished Material Design Java application, and to deploy it on an Android device and an iOS device with exactly the same code used in both deployments.

Asynchronous programming in Java 8: Jose Paumard explains how the patterns introduced by this interface and its implementing class are new to the Java platform, and how they fill the gap in the old Future patterns.

Java SE 8 for Java EE Developers: David Delabassee presents powerful Java 8 APIs such as Lambda expressions, a new Date and Time API, the Streams API, Completable Futures, Nashorn, Repeatable Annotations, String joiners, etc.

Introducing Groovy

Oracle developer Jim Driscoll has a new article up on otn/java, titled “Introducing Groovy,” that shows readers how to master the basics of Groovy, a general-purpose scripting language that runs on the Java Virtual Machine (JVM) – and, as Driscoll emphasizes -- one that can largely be viewed as a superset of Java.

He presents a “Hello World” program that can be understood as either a Java or Groovy program and will compile and run in either environment. Driscoll takes readers through the intricate connections and disconnects between Java and Groovy. For example, Groovy is public by default and “Groovy deals with String objects using double quotation marks with strings” which “allows for variable substitution”. And, “there are also strings with single quotation marks.”

Driscoll illustrates his points with copious code that illustrates how Java developers can tweak their own knowledge of Java to take advantage of Groovy’s strengths, so that, by the end of the article, the (Java-informed) reader more or less understands Groovy.

Check out the article here.
