Functional Programming with Java

The 2 day Functional Programming with Java 8 course is aimed at developers who have been using Java but would like to get more out of the language given the new paradigms. They understand Java syntax, language constructs, distinctive object oriented characteristics but would like to start thinking in a functional way.

This course is designed to help developers think of Java in a functional way. Mutable variables, exceptions, classical input/output, and all other traces of impurity are eliminated. Building up from first principles and extending all the way to incremental input and output, developers would be able to express every concept using only pure functions. This leads to beautiful code and deep insights into the nature of computation.

The course has a practical focus, mixing presentation with in depth hands on labs and exercises.
