From the NYT:
Local amphibian fans can be forgiven for not noticing the new frog's unique nature. "I wouldn't know which one I was holding because they all look so similar," said Ms. Newman, who is now pursuing her Ph.D. at Louisiana State University. "But all of our results showed this one's lineage is very clearly genetically distinct."
No nullable primitive types.
They have them for primitive types, actually, and had for ages - java.lang.Integer for int etc.
No, that's not the same thing. Integer (and Long, etc) are objects, not primitives. The GP's point was that in Java you can't say e.g.
int i = null;
I've not tried that (and don't have a JDK installed on this machine) but I would expect a compile-time error. (I've not tried it in C# either for that matter)
What is worth doing is worth the trouble of asking somebody to do.
