Pragmatic Functional Refactoring with Java 8

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 your existing codebase?

In this talk, Raoul will show how you can refactor your traditional object-oriented Java to using FP features and APIs from Java 8 in a beneficial manner. He 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.
