And a stripped-down non-existent API is a way to make things simple? Pretty much all modern languages have very detailed and complete API/framework, and all for the same reason: Why should a programmer have to re-write common routines and data structures for every program? Why bother using a big external library (which can just becomes another dependency) when it can be built into the runtime?
Horse and buggy carriages were much simpler than complex modern cars. We should probably go back to those.

Nope. Einstein said it best, I think:
It's a given that new features will increase complexity. (Which, surprisingly, is not always true. But stick with me for a moment.) The key is to increase the complexity only as much as necessary. If you increase the complexity any farther, you have failed.
I can't count how many times I have seen code that is overly complex. e.g. Someone piled up layer upon redundant layer of code, hoping to get simplicity out of each one. Instead, they create more maintenance, more points of failure, and more bugs. Probably one of the most egregious examples was a company that wanted me to use a go-between piece of software on another server to make a real-time request for XML. They had a lot of weak excuses for this decision, not one of which held water. After peeling back the layers of nonsense, I found out that the reason why they wanted it used is because they had already sunk $10,000 into it.
While not all examples I've seen are motivated by money or CYA, I have certainly seen a lot of examples that were motivated by blind adherence to company standards or existing technologies. Never mind that this particular module doesn't need any of the features of Struts, the company policy says use it, so we use it. Never mind that ADO isn't a good API. We have it, so we should wrap it. Never mind that we could just plug in a lib to do the secure transfer directly, we need to Rube Goldberg it through 5 different machines, protocols, and scripts written in 7 different languages!
There's a reason why engineers harp on the KISS principle. KISS is all about engineering a solution that will last for a long time to come. A solution that can be understood by others, maintained, is reliable, and exceeds the specs wherever reasonable. As Einstein said, make it as simple as possible and no simpler.

I hate to break it to you, but there is a great deal of business that is done on Microsoft software. There are a number of reasons for that (admittedly, not all of them are good reasons). One of them is that MS has done something Linux and the others haven't - they make software that makes it fairly simple for most businesses and people to do 80% of what they need to easily. In addition, needs which are not met by MS itself, and a number of needs which are, are covered by various 3rd parties.
As for "toys to keep you occupied", I'm one heck of a lot more productive using C# in Visual Studio for most of the things that I have to do than I was using C or C++ in xemacs. C and C++ are fine tools for doing things closer to the metal. Most applications don't need that.

The rest of the Java API is also not bloat. There are libraries for printing, crytography, sound, graphics, DOM, file I/O, text parsing, text formatting, text display, mathematics, directory interfaces (e.g. LDAP), distributed object systems, reflection, security, SQL database interface, logging, cross-platform preferences, regular expressions, ZIP/GZip support, accessibility, networking, the compiler, scripting engines, etc., etc., etc. Very little of the core API is redundant, with most of the (few!) redundancies being a result of the early days of Java before they moved away from the C++ style objects.
Nearly all of the post-1.0 APIs were done correctly the first time. Which means that the core Java API is actually quite slim for the amount of functionality it provides. And even then, there is a HUGE number of official expansion APIs for mail, multimedia codecs, network request/response handlers (e.g. servlets), 3D graphics, 3D sound, text-to-speech, speech recognition, telephony, SOAP, REST, USB, Bluetooth, scientific units, cross-platform desktop integration, Instant Messaging, P2P, and quite a bit more. And that's just the official JSR-approved expansions! The OSS and (bleh) commercial worlds are full of unofficial libraries to deal with nearly any problem you can come up with.
If you want bloat, stop looking at Java. Try compiling a few Linux apps sometime and tell me how many redundant libraries you come across. If you know what they all do (which is a miracle in of itself), compiling just ONE of those programs is enough to make a person blush with embarrassment. Not to mention that when a platform IS solidified (e.g. GNOME), it suffers from versionitis. (i.e. The constant need to upgrade your version of the libraries because this latest program no longer targets the version you just compiled. Or even worse, it requires a specific minor release, thus requiring you to have multiple minor releases of the library compiled and installed.) I won't even go into Microsoft's practice of inventing a new API for the same technology over, and over, and over again. (ODBC, DAO, ADO, JET, anyone?)
Now I happen to think that a lot of the choice that Linux offers is good. But don't point fingers at other platforms when there are more than enough examples of far worse situations close to home.

Creating a new type abstracts away complexity and makes code easier to read. For example, you will often find that business software does a lot of comparing of dates. e.g. Checking whether a date is within a given range. More often than not you will find that programmers have just written things like...
The logic of checking that dates are in a range is repeated all over the place and the more you have to type, the more likely it is that you will make mistakes. This is where adding a new type, a "Range" type will help. With a Range type you can just say something like...
So adding a Range class actually reduces complexity rather than increasing it. There are plenty of examples of this sort of thing. Imagine writing a car ordering system without having a Car class to abstract away details about cars. You could do it, but the code would probably be a lot more sprawling and complex.

Re:Wow, that's a big fat ASS^H^HPI (Score:5, Insightful)
You seem to be assuming that there would be a hard coded range. The allowable range may be defined in a database or elsewhere. Checking against the same range may occur in many different places, so you certainly would not want to have the range hard-coded in every routine you need to do such checking.
Imagine that the Date range object was intended to check the date of birth of new employees (e.g. You want prevent mistakes like they were born 200 years ago or 50 years in the future). If you are smart you will have created some kind of Employee class, and this Date Range checking object could just be a static variable of the class itself. It would be pretty easy to see where it was set.
The whole point is to reduce the unnecessary repetition of logic. Imagine if you wanted to do something more complex like check if one date range was contained within another. Suddenly you start repeating quite a lot of logic without a Range object.
Of course there will be different ranges. What does that have to do with anything? If anyone names variables "Range1, Range2" etc, they need some quick re-education.
It's interesting that you think information is being hidden. This would only be the case if you compare it to the situation of hard coding things everywhere, which is generally a very bad practice. The information in a Range object is no more hidden that the case where your limits are two separate variables called "StartDate" and "EndDate" (Variables which might be initialized when the application first starts). What is really being hidden is logic. That's what object oriented programming is really all about, i.e. trying to abstract away complexity into new types.
It's not really mine. Martin Fowler wrote about it in Analysis Patterns, although I'm quite sure it was being used long before it occurred to him.

Look, in a class library that purports to help most everyone, there's going to be an awful lot of code. Class library implies that classes are used to organize the abstractions provided by the library. Proper OO design favors designing more types with smaller number of features rather than God-objects that do many things. Fine-grained objects are simpler to unit test and are much easier to reuse. The downside is the propagation of types and the verbosity level of the code generally goes up. But that is a fair trade-off in my opinion, since the most important work on the code happens in the maintenance phase, when someone else can come along and at least get a vague idea of what is going on.
