PLUS, Google report names Java “easiest to implement.”

Google Name Java “Simplest to Implement”

Google have published a research paper that compares the performance of
Java, Scala, C++ and Google’s own Go programming language. Google
implemented a specified compact algorithm in the four languages and
evaluated the results along “several dimensions.”Google concluded
that Java is “probably the simplest to implement, but the hardest
to analyze for performance,” particularly regarding garbage
collection, and found the same issues with Scala. Google also
decided that C++ wins out by “a large margin” when it comes to
performance, however, the report also stated that this language
requires the most extensive tuning efforts, many of which are at a
level of sophistication that is not available to the “average”
developer. The full report can be viewed now (PDF.)
