The course will start July 14th!

Enroll
If you are like me, you are an experienced Java programmer, and understand Java as an Object-oriented language, but you are not really familiar with Lambda expressions. You may also have watched Brian Goetz's talk, Lambda: A Peek Under the Hood from JavaOne 2012, but you didn't quite get it.

Well, now is your chance to join me and thousands of your peers to learn more about Functional Programming in Java using Lambda expressions and the Streams API in our latest free Massive Open Online Course (MOOC).  The course will start July 14th, and is short - just three weeks. But you will learn a lot, including how to:

  •  Apply Lambdas to everyday problems
  • Convert anonymous classes to Lambda expressions
  • Apply the Streams API to solve problems of sorting, identifying the most and least, and reducing duplicates
  • Determine when to apply Lambdas (and when not to!)
  • Use Collectors
  • Improve performance with parallel streams
  • Debug Lambda expressions

So click the Enroll button - read the full description of the course and watch the video - and I will see you on July 14th!
