neoitertools is a port of Python itertools algorithms and concepts to Java.

• It implements all the generators available in itertools:
  • range
  • groupby
  • filter
  • ...
• It implements the famous yield statement.
• It provides an Helper class to provide really clean code

for ( int i : in (range(10) )){ yield (i*i); } Read carefully, yes, this is pure Java ( I've just hidden the imports).

There is a lot more example.
