On this newsgroup there've been spirited discussions on this topic for years.

In my experience over the last ten years lots and lots of Java programmers, most 
of the ones with whom I've spoken, knew what closures were if they were reasonably 
competent Java programmers.

But I don't claim statistical significance for my non-random idiosyncratic sample. 
You should not either.

The fact that my experience is the opposite of yours should be evidence for that.

For the record, I argued vehemently against the addition of closures to Java. 

I tend to agree with Stefan here.

Wrong.

It is not enough.

Because people who learn only Java tend not to even program Java well.

That I've seen. I don't know if that has statistical significance.

But based on my experience and much reading and the advice of mentors, 
I will state unequivocally that knowledge of only Java makes a terrible computer 
programmer.

Simply terrible.

Any real programmer would have learned at *least* one other language, usually 
prior to learning Java, and would understand things like computable pointers.

Anyone who calls themselves a programmer and is unwilling to learn a second programming 
language is an ass and needs to switch to serving fries to fast-food customers.
