Lambda Tutorial & Reference - Table of Contents

This is a webpage devoted to lambda expressions in Java (a new language feature) and streams (new abstractions in the JDK's collection framework) - both were added to Java on March 18, 2014 with release 8. If you want to provide feedback or have any questions regarding lambda expressions in Java feel free to send me EMAIL or use the LAMBDA QUESTION form.
The Lambda Tutorial is available in PDF format (330KB) and in EPUB format (410KB) .
The Lambda Reference (note: it is an incomplete draft version) is available in PDF format (1200KB) .


Keep in mind that part of the Lambda/Streams Tutorial & References is still in draft version.

Lambda Reference

(to be done)
 

So far there is only a pdf version of a incomplete draft of the Lambda Reference. It is 90% complete; the last chapter on the "Runtime Representation of Lambdas" ist missing.  The reason simply is that  features such as "Serialization of Lambdas" have been moving targets until just recently.

If you are interest in reading the pre-release version of the Lambda Reference you can download it here .  Feedback is welcome; send me EMAIL or use the CONTACT form to get in touch.
