Two Hours of Video Instruction
Many Java developers today are working on applications written before the release of Java SE 8. Even after Java 8 is adopted for new features, it’s likely that these legacy applications will not take full advantage of Java 8 without significant refactoring.
In Refactoring to Modern Java LiveLessons, Java Champion Trisha Gee discusses the benefits of using Java 8 and shows how to identify code to refactor. She also demonstrates how Java 8 can improve performance and the benefits of applying Java 8 idioms. In this video training, Trisha provides hands-on techniques using a real application, Morphia, written in Java 6, to show when and how to apply the new features in Java 8 to an existing mature code base.
