JVM: Java 7 In Action: Using New Java 7 Features In Real Code

This session will describe several new features introduced in Java 7, including a couple of the "Project Coin" language features. These features will be described and their benefits shown by using them to improve an actual piece of code from the JDK. The features to be shown are try-with-resources, more-precise rethrow (which are two language features introduced by Project Coin), and one of the new NIO utilities. The presentation will begin by showing a single method taken from the JDK 6 code base. It will continue by applying the features one by one using NetBeans, including an explanation of the feature and of its significance. Finally, the "before" and "after" code will be compared. The resulting code will be more concise and more correct than the original, showing that the new Java 7 features offer the opportunity to make great improvements to your Java code.
