Although support for Streams was added to Java almost seven years ago, providing a breeze of fresh (and functional) air, few people have dived into the world of creating their own Collectors. This workshop will explore the possibilities of custom Collectors, showing you:

-       A brief reminder on Java Streams and the role of Collectors within them

-       Different real-life scenarios where a custom Collector can improve the code by embedding common checks, filters, and transformations into the Collector itself

-       How to create a Collector from scratch

-       How to create a Collector by extending an existing one

-       How to parameterise Collectors so they can adapt to different situations

-       How to test and share Collectors

-       How to deal with the additional challenges of parallel Stream processing

By learning how and when to create your own Stream Collectors, you will be able to create code that is more closely aligned to your needs, making it more readable, reusable, safer, and testable.
After this workshop, you will never look at Collectors the same way again.
