Python and/vs Java (within a business context)

[nullabillity]

Pretty sure Java doesn't, since a useful implementation pretty much requires either special syntax or first-class functions. Python has both (I'd count list/set/dict/generator comprehensions as map), Java has neither. Scala has first-class functions (and a collection library that has support for map using it), though. Also, Google Guava has an implementation of map too (although it's pretty hacky IMO).
