I will say, I'm only back into Java for a week, and even in spite of Java
generics and inner classes and all that, I'm already much more appreciative
of how much crap MS fixed in C#. :-) Stuff that's taking me 4 or 5 lines,
with the types repeated three times each, is a one-liner in C#, even without
LINQ.

yeah, I like it how MS took ideas from Python and Haskell too.

Now you know why I dislike using languages which aren't Haskell...

Last time I used Java, we did a little dance. It went like this:
"Object-oriented programming allows you to use facilities such as
subclassing to extend the application in ways the original designers
never anticipated."
"By declaring your class 'final', you can prevent anybody subclassing it."
"Multiple inheritance is EVIL! We support only single inheritance."
"We support multiple inheritance using 'interfaces'. They're like
classes, but not as good."
"For receiving input, use the InputStream classes. For output, use the
OutputStream classes."
"For receiving input, use the Reader classes. For output, use the Writer
classes. The InputStream and OutputStream classes are now formally
deprecated. (Even though System.in, System.out and System.err mention
them explicitly.)"
"We will never deprecate the AWT."
"The AWT is now deprecated. Please use Swing in new applications."
"To create a horizontal scrollbar, create a Scrollbar object passing the
SCROLLBAR_AXIS_HORIZONTAL static constant. To create a vertical
scrollbar, create a Scrollbar object passing the SCROLLBAR_AXIS_VERTICAL
static constant. To determine whether a given scrollbar is horizontal or
vertical, call getAxis() and compare against these static constants. Do
not hard-code the numerical values, as more may be added in future."
"The 'int' type is not a class."
"If you want 'int' to be a class, you must wrap it using the 'Int' class."
"The int[] type is a class."
"For structuring complex applications, use the ApplicationFactory class."
"The ApplicationFactory class is now deprecated. Please use
ApplicationCenter for new."
"The ApplicationCenter class is now deprecated. The ApplicationFactory
class has been formally UNdeprecated. Please use ApplicationFactory for
new applications."
Basically, the language is loaded with hypocrisy, and the libraries were
huge, bloated, overly complex, insufficiently documented, and prone to
radical alterations every minor point release. (In fact, I gather that
these days, they don't even call it Java 1.5.x any more. They just call
it 5.x...)
Last time I checked, java.awt.Component has about 80+ methods. Every
single AWT widget inherits these 80+ methods. Any guesses what the hell
the difference between widget.init(), widget.start() and widget.begin()
is? The documentation helpfully fails to say. (E.g., "start() - starts
the widget." Yeah, thanks for that. I gathered.)
It still amuses me how almost every statically-typed programming
language lacks parametric types, /except/ for arrays, which are
hard-wired into the language.
(It still makes me cry that Haskell to this day still doesn't support
parametric unboxed arrays - you know, like what almost every programming
language known to man /does/ provide, out of the box...)
In Java, "int" is not a class. But "int[]" is. In fact, every array is a
class. And you cannot ever subclass it.

I love the way that with the JDK, compiling a class compiles every class
it depends on, but declaring two mutually-dependent classes is enough to
break the compiler. I wonder if they fixed that yet?
I love how you run your Java applet in IE and it works perfectly, and
when you run it in Netscape it dies with java.lang.NullPointerException.
I love how we have System.err (because System.error would be far too
verbose), and yet we have java.lang.ArrayIndexOutOfBoundsException.
Because, say, java.language.exception.ArrayIndex would be too hard?
I still think that Java is a great /idea/ - you specify a programming
language and a library of classes which is guaranteed to work the same
on *all* platforms. That's a very neat idea.
I also still think that the actual Java /design/ and /implementation/
utterly suck. Nice idea, too bad it went so drastically wrong from
thereon in.
(I suppose you could argue that C# is the same. You know, if it actually
worked on more than one platform...)

Does Mono support more than 0.2% of what .NET supports yet?

Yes. Go read the mono page and see what compatibility is.

Oh, wait until you use some "dependency injection". Then you'll have *no*
idea how your code is structured. You not only get the indirection of
factories making other factories, but the factories you're depending on
aren't even compiled at the same time as everything else. Good luck figuring
out what you're trying to instantiate.

Yep, yep. Altho MS has been starting to do that sort of crap lately too,
I've noticed. The first release of Java had identical documentation for
StreamReader and StreamWriter, because they did the cut-and-paste and forgot
to change "read" to "write" everywhere.

I did some code yesterday where I had to break one type name over multiple
lines to keep within the 80-character line limit standard. It doesn't help
when you have stuff like
FastPersistentLinearCollection<OrganizationIndividualRelationshipEntity>
I kid you not.

It just amuses me that they thought the current design was bad, so they
deprecated it and build a better replacement. And then they decided the
repliacement was worse than the original, so they UNdeprecated it. I
mean, WTF?

I notice Office no longer comes with any documentation at all, just a
link to an online forum. (So if you have no Internet access, there's no
documentation AT ALL.) That's a nice touch... Why pay for experts to
write correct documentation when you can get your users to spread
erroneous twiddle for free?

Yep. That's the great thing about embedding documentation in the source
code; it keeps the two in sync.
Oh, wait...

LOL. At least VisualStudio J++ got that right... (Oh, wait, Sun sued
Microsoft to make them discontinue that product.)

It has documentation. It just mixes it in with the online forum. I think you
have to chose to install it locally, tho, which is what you might be seeing.

It makes perfect sense in context. It's just absurdly verbose.
What would be in C#
var z = from y select z where z.id = myID
in java becomes
List<OrganizationIndividualRelationshipEntity> z =
Lists.ImmutableCopyOf(
Lists.filter(y, new
Predicate<List<OrganizationIndividualRelationshipEntity>() {
@override boolean apply(OrganizationIndividualRelationshipEntity x) {
return x.id = myID;
}
}
)
}
I've lost track of closing braces....

I wouldn't mind, but it didn't even /work/.
Like I said, I wrote an applet. It worked fine in IE. When I tried it
with Netscape, it crashed with a null pointer exception. And, since it's
an applet, I have no idea /where/ it crashed. You don't get a stack trace.
I suspect this is probably related to the vagueness of the
documentation. That means that others don't really know how to implement
it correctly. Or, hell, maybe the documentation just doesn't actually
match what Sun implemented...

Yeah, at least more than 0.2% probably by a substantial amount. But I
can't be bothered to target the Mono framework, honestly, I'll just
stick with MS's CLR.

It may be that some bug in the implementation under IE is effectively
hiding another bug...
It may be that you get the crash on the correct implementation and you
did something wrong that made it work on a faulty implementation.
Remember the imfamous "it's not a bug, it's a feature" that Microsoft
spun to cover actual IE bugs instead of correcting them.

Considering the applet only makes a handful of AWT calls before doing
lots of compute-bound stuff to generate a fractal... I'm pretty sure it
was just some unimplemented library call returning null or something
like that.

Haskell has crazy type signatures too.
Haskell also has mechanisms for defining shortcuts. :-P

You don't understand. Those *are* the shortcuts in Java.
No, I am not exaggerating. For example, "Lists" is nothing but a static
class full of static routines that are shortcuts for actually shortcuts for
the more full-bodied declarations including all the generic types.

problem is that you're trying to make java look worse than it is (and I
agree it is bad) by programming it in a functional style it simply is
not meant to. Java is all about imperative programming at its worse,
but at least it makes some sense when programmed that way.
I'm not quite natural to java, but I guess the correct way to program:
var z = from y select z where z.id = myID
in it would be something like:
List<OrganizationIndividualRelationshipEntity> y, z;
for (OrganizationIndividualRelationshipEntity x : y)
if (x.id = myID) z.add(x);
that doesn't look half as bad as trying to program C in Object-Oriented
fashion. Still, not as fun as without type declarations. I suppose if
the code snippet was inside some generics method you could call
"OrganizationIndividualRelationshipEntity" "T" and have:
List<T> y, z;
for (T x : y)
if (x.id = myID) z.add(x);

Well, it's the way this particular project at google was written. But yes,
making Java functional without lambdas is messy.
I went thru something like 300 classes in this particular hugely
overengineered project and didn't find a single noun in the bunch of them.
They were all stuff like "CustomerUpdater" and "StorageManagerImplementor"
and such. I think it comes from doing too much networking, since networks
don't do a real good job of shipping objects around. I've been trying to
introduce the team to the wonders of actually having the code and the data
in the same class. :-)

Well, from the old relational database experience... they shouldn't.
At least, they shouldn't be too tighly coupled until the code is
specific to the data and the data are usable only by the code.
Have a SQL schema (data) and only stored procedures usually ends up in
nightmare.
Data should have their invariants and rules.
Code should be in charge of transforming the data with respect to the
rules and adding new pieces of data which also match the rules.
But you're right, having data in very distant classes from the ones
which have the code is also a PITA. (and from an isolation point of
view, the code classes should not be friend of data class, so no ugly
shortcuts...)

Well, the data in the database shouldn't be exposed to the user at all, any
more than if your web site is stored in a database the browser should need
to know that.
What I'm saying is that if you have a routine that (for example) marks a
video as having been watched by the current user, it shouldn't be in some
third class called "VideoWatcherRecorder" taking an integer video number and
a long user ID. It should be in the video class and take a reference to a
user object, or vice versa. Otherwise, you're just writing procedural code
in Java.

Yep. And that's very hard to do without doing OO programming. Or relational
programming. And if you're using an OO language like Java, it should be
enforced in the objects that interface to the database (along with the
database, if possible, which it isn't in this case).

Sure. But the difference is where that code live. Is it in some other
package or compilation unit, or is it in the same class that reads and
writes the database?
