What do Java programmers feel is missing from C#?

[mc]

I may be opening a can of worms and don't want to start a religious war,
but...

What features of Java do Java programmers miss when working in C#?

Other than, of course, great portability. C# has more limited
cross-platform portability (Mono).

I'm thinking more about data structures and ways to express algorithms.

I sort of liked fall-thru in switch statements, but I'm the first to
admit that it can lead to unreadable code.

The Java Language Reference mentions something called a Duff's Device,
which I never really understood and which C# would probably frown on
anyway. :)

Actually, I think the switch statement is the most awkward thing in C#,
largely because it isn't the Fortran-like thing from C that it looks like.
I wish C# had adopted the Pascal case statement.

I am just esthetically prefer Java. I think Java is simpler language.
There is no properties, no defined operators, no delegates - for me it
makes everything more clear. I know only one language that is comparable
in transparency - C.
I also liked Java collections Api and general API more - just preference.
Java has checked exceptions and this makes dealing with exceptions more
easy - you mostly know which exceptions you can expect.
JavaDoc - is more clear that C# XML Docs, and in my opinion leads to
better quality API descriptions.
I prefer Java Strict package / folder structure to unclear C# conventions.

But I seem to recall (good grief, I learned Pascal in 1981) that the
Pascal case statement had no default/otherwise/else, right? Well, I
don't think it did on that creaking Univac we used, but I just Googled
it and and I guess other flavors of Pascal did support it.

See also Brian Kernighan's famous paper about Pascal at:

http://www.cs.virginia.edu/~evans/cs655-S00/readings/bwk-on-pascal.html

One bit of trivia about the Java default (I think) is that it can occur
anywhere in the case sequence, even at the top.

Yes... when I say Pascal I really mean Turbo Pascal and Delphi. Early
Pascal was impoverished in some ways, as Kernighan pointed out in the paper
you cite.

Well now that just has to be the IDE... Visual Studio is just so 1990's

I miss the slow performance of Java and overall lack of productivity
and the vast amount of crappy offshored leftover code I used to work
on.

I get so much more done in C# it leaves me longing for that crappy
Java environment I left behind.

I did a quick Google search for "java c# benchmark" (try it yourself)
and it seems that it's only that offshored code that is slow and crappy
and not Java itself, because all benchmarks I could find concludes that
Java is way faster than C#.

Ah, the fast pace of modern life :)

Likewise, a whole generation of office workers longs for the days of snail
mail instead of e-mail, so that we would actually be allowed some *time* to

Well, this one:

http://www.manageability.org/blog/archive/20030520%23p_the_problem_with_cameron

is the first one that comes up, but obviously something has gone wrong. A
factor of 7700 speed difference? They're just not measuring the same thing.
If C# were 7700 times slower than Java, it would be unusable.

I'm going to explore this and see what I can find out. A quick test shows
that his C# program is indeed woefully slow.

Quick preliminary answer: Both of the programs measure the time taken to
*compile* a regex, not the time taken to run it. The two compilers are
probably doing very different things.

It's like dude went very far out of the way to find some bizarre
benchmark to suit his goal. Who uses compiled regexs in c#
applications?

Those guys are called COBOL programmers, and they make the big bucks
:)
