Your Programming Language Sucks?
Email
Update 2012-June-20: Please also read my follow-up post, Revisited: Your programming language sucks?
I met someone recently that declared “Java sucks.” One proffered argument of that “suckiness” was Java’s lack of expressiveness. In point: you can’t compare two Date objects with the less or greater -than operators. Further, you can’t override the operators themselves. (I won’t touch that subject; we covered it in Computer Science 201.)
Date now = new Date(); Date epoch = new Date(0); assert now > epoch; //won't compile
Nope, that won’t compile. What are we to do?
assert now.after(epoch);
There, that works. But what if we really, desperately wanted to use operators?
assert now.getTime() > epoch.getTime();
Both of these seem perfectly expressive to me. Much ado about nothing? I think it’s a matter of comfort and familiarity.
Saying a programming language “sucks” says less about the language and more about the person speaking.

Hi Mike,
I'm sure you'd agree that for whatever it is that you're trying to achieve by programming, Malbolge would suck. COBOL too, perhaps. Yes, that says something about you, but let's not pretend as though it's impossible to make qualitative assessments about programming languages, especially given a set of criteria. Who knows, your problem domain might be such that it would be wildly impractical not to have operator overloading. (For example, I've found it irritating that I couldn't use + on Java's BigIntegers. If you're doing a lot of matrix computations, syntax like MatLab's is nice.)
If the person you're referring to made his 'Java sucks' case based solely on the impossibility of comparing two Dates, especially without mentioning why this might be important to him, then yes, that might make for a somewhat feeble argument. (I mean, everybody knows how swell Java's Date API turned out, don't we?) That's not to say there aren't a lot of things wrong with Java, as there are with most programming languages.
I personally don't have the things you mentions very high up on my list of reasons for not using Java, but I always find it instructive to learn about other people's criticisms. Surely you have your own list of Java peeves and secret wishes?
On a side note, I don't recall a CS class mentioning why operator overloading is bad. Perhaps you've had some problems with the C++ interpretation? The question of when to use it is quite a subjective (and orthogonal) one, as you hinted.
Cheers,
Erik

COBOL is probably the most expressive language in existence:
DISPLAY "Enter student details using template below."
ADD YEARS TO AGE
It's also can be faster than C/C++.
"Expressive" is a dumb argument. You need a level of it, but beyond a certain level it's pointless.
