Java Magazine - March/April 2016

Dear Reader,
Welcome to the March/April issue of Java Magazine
in which we dig into the inner workings of Java
and the JVM. This issue is pure nerd-stim: bits
and bytes have never been as much fun as
exploring how the JVM manages garbage collectors
and code caches. All good developers are mindful
of how their code executes, but due to constant
advances in the language and the JVM, knowing
what's going on behind the scenes is not always
easy.
So, let's dig in. We start by looking into the
fundamentals of just-in-time (JIT)
compilation in the JVM, we compare the
performance of different garbage
collectors, and then we update
an article on the JVM's code cache
and its effects on performance. To these, we add
deep dives into how Java itself works: how annotations
are handled and how to write your own
annotations; plus we examine how the Java
Collections Framework
was optimized using laziness, which is a
technique that is available to you in your code.
The rest of the issue shows off Golo,
a new JVM language; better persistence in Java
EE; and how enums work in Java--all topped off
by our famous language quiz, our no-holds-barred
book review, and my editorial,
which discusses a new proposal by the Java team
to add greater type inference to the language.
Enjoy!
Note: In our quest to support more
devices, we have moved away from the former Java
Magazine app. Currently, the magazine is
available only on the web and in PDF. To get the
PDF, access the web page from a laptop or
desktop and use the download icon on the right
side of the page.
Like what you see? Wish we'd cover something
else? Please send along your feedback, which I
read attentively. You can always reach me at [hidden email].
