Java 8 Functional Programming: Lambda Expressions Quickly
- You should already know Java 7
This is a very rapid course on Java 8 functional programming.
Functional programming has been the most important of all Java 8 new features. Using Java 8 functional programming, we can now code many things much faster than before, in a concise, fluent and readable manner. But, unless you learn those functional programming features properly, getting used to those becomes a bit confusing. So, in this course, we are going to grasp how to do functional programming in an intuitive and conceptual manner, very rapidly. We'll learn each feature with simple and crisp examples, which'll be very brief but quite informative.
This course is actually part I of a two-part course. It covers about Java Lambdas, e.g. lambda expressions, method references, composing lambda expressions etc. The next part, which is coming soon, will be about Streams. You'll find link to that in the resources section of the last lesson.
We've done some practical exercises in the lessons here, and the links to the source codes are available in the resources section.
Who this course is for:
- Anyone who wants to grasp the concepts of lambdas and use those confidently in 30 minutes
- 04:05Passing Behavior
- 04:29Introducing Lambda Expressions
