Kotlin: Making JVM a Better Place

Excerpt

Learn about Kotlin — a modern programming language targeting JVM (and JavaScript). Kotlin not only interoperates transparently with Java and re-uses all the existing Java libraries, but even allows you to make those libraries _better_. This session demonstrates how existing Java libraries may be enhanced in Kotlin.

Description

Kotlin is a statically typed general-purpose language with lots of modern features that make it safe and expressive. It is developed by JetBrains (creators of IntelliJ IDEA) and distributed under the Apache 2 license.

This session demonstrates Kotlin’s interoperability with existing Java code. It is possible to develop “mixed” projects where Kotlin code calls Java and vice versa. On to of that, you will learn how existing Java libraries may be enhanced in Kotlin by adding

  • extension functions for missing handy operations,
  • overloaded operators, such as ‘+’ or ‘[]’,
  • higher-order functions for internal iteration, and map/reduce,
  • builders for declaratively specifying data.
    And all that for familiar Java collections, IO, Swing and more!

Speaking experience

I've presented at JVM Language Summit, OSCON, StrangeLoop, Devoxx. Links to all the talks (most of them with videos) can be found here: http://confluence.jetbrains.net/display/Kotlin/Talks+and+Publications
On top of that I did quite some lecturing in college and high school.

To date (Jan, 2012) I have not given this talk before, but I submitted it (and closely related) to a few places.
