Ok, so there's a bunch of problems with the Java version.

- In addition to the addRow run and the Java startup time you're also
benchmarking over 5200 array modifications to set Compared values to true
- Your variable naming is entirely contrary to every Java coding convention
published (not a benchmark thing, but it sets off any Java devs warning
flags)
- Almost all of the time spent running is spent building and printing
strings

Benchmarking just the algorithm run itself with no gross string creation and
printing, I'm getting in the neighborhood of 370ms per invocation once
HotSpot has optimized the code. I'll have more detailed numbers shortly.
