- Functional Programming With (or Without) Java Streams: A Case StudyOracle, Burlington, MA
As a Language, Java has evolved to incorporate gradually more functional programming (FP) features. For instance, the old "switch" statement, inherited from C, is slowly turning into a full-fledged pattern-matching expression, as could be found in a truly FP language. Most notably, streams (combined with lambda expressions) are sometimes hailed as having brought FP to Java. It is true as far as simple illustrations go: using streams, you can now square all the numbers in a list with "map(x -> x * x)". But real applications need more than squaring numbers. What happens then? In this talk, I will describe several attempts at implementing a classic FP strategy using Java code. In particular, I will show how well (or not) streams fit the needs of the program, and what alternatives can be used. The talk will be Java-centric with plenty of code (available on GitHub).
