If Streams Are So Great, Let’s Use Them Everywhere... Right?? by Maurice Naftalin, José Paumard

Maurice Naftalin and José Paumard compare imperative and functional styles in Java, debating where streams excel and where they fall short.

Using streams everywhere: is that really a good idea? Certainly, stream code is often much clearer and more concise than iteration over a collection. But sometimes a stream solution requires a complex combination of collectors, reduction over a primitive stream, or nested FlatMap operations, and the verdict isn’t so obvious. In this talk, we’ll look at some sample use cases, evolve the best solutions we can, in both imperative and functional styles, and then argue over which is better. You’ll get a vote too!This session is for everyone who needs to write code in Java for bulk data processing – every Java developer, in fact. You’ll leave hopefully entertained, and with a better idea of the use cases where streams excel, and where you’re better staying with old-fashioned ways.
