Silly Metrics: The Most Used Java Keywords

· Java Zone

The Java Zone is brought to you in partnership with AppDynamics. Discover how AppDynamics steps in to upgrade your performance game and prevent your enterprise from these top 10 Java performance problems.

Tell me…

  • Haven’t you ever wondered how many times you actually “synchronized” something?
  • Didn’t you worry about not using the “do {} while ()” loop structure often enough?
  • Are you an expert in applying “volatile”?
  • Do you “catch” more often than you “try”?
  • Is your program rather “true” or rather “false?
  • And how did that “goto” make it into your source code??

Here’s a bit of a distraction among all the other, rather informative posts I’ve written recently. An utterly useless ranking of the top Java keywords in jOOQ. I mean, after all, useful metrics can already be reviewed at ohloh, or collected with FindBugs and JArchitect

Now, you can figure it out. Here’s the ranking!

Use it, and publish your own rankings! And feel free to provide pull requests to count keywords from other languages, or to calculate entirely different silly and useless metrics.
