Mark Reinhold recently blogs about the renaissance of
closure in Java (*).
In his blog, he also wrote that in order to have closures in Java,
Java will have to include another feature named
As you may already know, I'm a big fan of closures but
the introduction of extension methods in Java really scary me.
* Ok, they are more lambdas than closures.
Java VM embodies

This post shows how to write a non-blocking server with continuations.
Why using continuation with non blocking IO
There are two models when you deals with IO:
the thread model: read and write calls block until they at least read one caracter or write the whole buffer,
so one use thread to be able to...
Lukas Stadler is my hero, at last JVM summit, he just explain how coroutine and friends can be implemented in the VM and guess what, it now works (currently only with C1).
Let's try to implement something with it.
I have always wanted to have generator in Java. After all, Python have this feature, Ruby and C#(*) too.
A generator is a way to define an iterator but instead of...
It seems that "lite" closure will be in JDK7.
I really don't care about the surface syntax but I hope that the runtime of such closure will be on top of JSR 292 method handle.
As you perhaps already know, jdk7 milestone 5 (jdk7b76) is
This new milestone contains a lot of bug fixes and improvements.
This blog entry is about two of them:
Strings in switch
Method handles (yes again)
Switch on String
This one of the small proposal changes (from
Coins's project) to Java language in order to
allow to switch on String values.
Let's take an example...
Let me introduce a new language named pseudo (Why this name ?
Why another language ? Why God ? all these questions will be answered
in a later blog).
One great feature of this language is that it allows
i.e. you can assign a type to a parameter, a local variable, etc.
If a variable as no type, the compiler consider it as any.
You can assign any value...
