Pragmatic Functional Refactoring with Java 8

Conference

Java, JVM, Javas SE/EE

Main Keynote Room

Wednesday at 10:15 - 11:15

You may be hearing a lot of buzz around functional programming. For example, Java 8 recently introduced new features (lambda expressions and method references) and APIs (Streams, Optional and CompletableFutures) inspired from functional ideas such as first-class functions, composition and immutability. However, what does this mean for my existing codebase?

In this talk we show how you can refactor your traditional object-oriented Java to using FP features and APIs from Java 8 in a beneficial manner. We will discuss things like:

How to adapt to requirement changes using first-class functions.
How you can enhance code reusability using currying.
How you can make your code more robust by favouring immutability over mutability.
How you can reduce null pointer exceptions with Optional.
