Pragmatic Functional Programming in Java 8+

Pragmatic Functional Programming in Java 8+

In this workshop, attendees will learn how to supercharge their everyday Java programming experience by utilizing pragmatic Functional Programming ideas – which allow writing readable, predictable and less error-prone code faster.

The course is aimed at Java professionals who want to quickly break the cognitive barrier of making a paradigm shift and get up to speed with new tools.

Testimonials

Excellent teacher, lots of exercises which go beyond the common stuff… and lots of additional exercises which you can explore after the workshop. I learned how to properly use “functional” java in my daily job. Thanks for the amazing workshop!
