While we’re drawing ever closer to Java 9, and even hearing about features in Java 10, 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 that 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. And this is a shame, since Java 8 provides not only nicer syntax for developers, but (usually) better application performance.

In this presentation, Trisha will:

• Highlight the performance 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, and how to pick which changes will give you the most benefit
• Demonstrate 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 suggestions of when refactoring may NOT be the best idea.
