Java 7 is here!

I've been looking forward to Java 7 for a long time and it is finally here! This release is jam-packed with new features and I am really excited about trying it out!

There are great additions to the concurrency package such as a fork/join framework, phasers, transfer queues and threadlocal pseudo-random number generators.

Also, as part of Project Coin (JSR 334), JDK7 includes a set of small language changes intended to simplify common, day-to-day programming tasks and reduce boilerplate such as:

  • Strings in switch
  • Binary integral literals and underscores in numeric literals
  • Multi-catch and more precise rethrow
  • Improved Type Inference for Generic Instance Creation (diamond)
  • try-with-resources statement
  • Simplified Varargs Method Invocation
For a full list of changes take a look at the release notes.

I'm going to be writing about the new features in Java 7 as I learn about them, so stay tuned!

  1. Hi Daniel! Yes, I've read about this bug, but it doesn't meant that you can't try out some of Java 7's great new features. I wouldn't recommend upgrading a production critical system to it just yet though ;) Thanks for reading.
