Anticipating Java 9 - Functionality and Tooling


Seems like we’ve been waiting for Java 9 for eternity. We’ve been hearing all about Jigsaw since Java 7, so we’ll be forgiven for thinking that’s the most interesting thing about the next Java release. What we should be wondering is, will Java 9 it change the way we develop, like Java 8 did? Will my tools break when I try to use it? Is it worth playing with it before it comes out, or should I just wait until everything stabilises?

In this talk, Trisha will take a look at some of the features in Java 9, including modularity, the REPL, and the nice new Collections features. Trisha will demonstrate, via live coding, these features in IntelliJ IDEA, and talk a bit about the current and future support for Java 9 in IntelliJ IDEA.

Refactoring to Java 8


While we’re drawing ever closer to Java 9, and even hearing about features in Java 10, it’s also true that many of us are still working with an older version. Even if your project has technically adopted Java 8, and even if you’re using it when coding new features, it’s likely the majority of your code base is still not making the most of what’s available in Java 8 - features like Lambda Expressions, the Streams API, and new Date/Time.

In this presentation, Trisha will: - Highlight some of the benefits of using Java 8 - after all, you’ll probably have to persuade The Management that tampering with existing code is worthwhile - Demonstrate how to identify areas of code that can be updated to use Java 8 features - Show how to automatically refactor your code to make use of features like lambdas and streams. - Cover some of the pros and cons of using the new features, including the impact on performance. At the end of this session, you’ll have a better idea of when refactoring can easily be done, and when it may NOT be a good idea.
