Java. Functional programming [OLD, 2017] ★ 4.902

The course was designed for beginner java developers and people who'd like to learn the functional approach to programming. If you are an expert in java or functional programming, this course will seem too simple for you. It would be better for you to proceed to a more advanced course.

The course consists of theories, examples, questions, and code challenges. You will need both reading and writing code skills, as well as a bit of patience to successfully complete the course.

The most important topics you will learn are lambda expressions, method references, functional interfaces, the composition of functions, stream API, currying, optionals, and some others.

To reduce your spent time on completing exercises, all I/O and some other operations will be added to your solution automatically. It will also allow you to focus on the meaning of the assigned tasks. Look carefully at each example in the theory lessons and you will be able to write your solutions faster.

If you find any mistakes or unclear text, please, let me know.

This is an old version of the course. The new version is available here. However, you can pass this version too if you'd like!
