Pragmatic Functional Refactoring with Java 8

JUGS LogoSpeaker portrait

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:

  • 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 design better APIs and reduce unintended null pointer exceptions using an optional data type
