Anybody else read the Java thing in the daily news?
-
Ten years ago my mother called me once and was talking to me about Java. Thats how big the Java (SUN) marketing machine was !!!! I never liked it much after that ! It was insane ... Everyone was talking about it but you COULDN"T GIVE AWAY java apps back then. No one wanted it. It was pretty bad...Java fan boys were everywhere. I use to piss them off every now and then and talk about C++ and even Visual Basic out-performed it. LOL .. It was fun ! However, I am hearing from reliable sources that on the Android it is pretty sweet ..

Hmmm... I was taught BBC BASIC at school, Pascal at college none of which I have pleasant memory's of, taught myself C (now, we have romance) before Uni, used C in every company I have worked for since (also a little VB6 for pretty buttons), I tend to use C# these days thinking about learning :java: though.

Java...I have never really seen the point of it, okay it was supposed to run everywhere with Java Virtual Machine (like .NET Framework on some things iPaqs, Pocket PC), not give you direct access to the hardware (like .NET annoying), be royalty free (like .NET Runtime). So all in all it has been replaced has it not (discussion in a Pub with Geeky friends led to "Why the ***** would you use Java, C# pretty much the same plus you can blame Microsharft when it goes wrong!) Plus all the hotshot Java people I know (2) came from C++ to Java back C++ a few years ago... Are there features of Java that aren't anywhere else, whats it unique selling point any one (don't want to start a war just interested.)
I used to work at a company that sold LARGE printers ($250k+ for a small one) and they used Java for the UI on the printer itself. I asked why they wanted to use Java there and the manager's answer was because if we change the hardware then the Java will still work. The part that the managers did not realize was that the printer was using a version of Solaris that had a custom kernel to talk and control the hardware. Changing the printer to anything else would be massive work, so the entire idea that they could change it to something else and the app would just work was kinda funny. I pointed this out and they didn't have an answer for it.

Java, like any computer language, can solve some problems; end of. It is neither better nor worse than any of the others, it is merely different, and is a 'good' solution to some problems. Sometimes the only reason to write a program in Java is "because it's the language I know best". Language bigots, like any other type (e.g. Mac bigots), are just sad bores. I have used C, C++, C# and Java * and am happy with any or all of them, each one has taught me something that I didn't know. *I've also written programs in machine code, assembler, Cobol, Fortran, RPG and a couple of others whose names I no longer remember.
One of these days I'm going to think of a really clever signature.

I primarily come from a Java background. Was the first programming language I learned (I also learned a bit of algorithm basics applied in C, but way too little to count). I always had the opinion that it was a simple and pretty straightforward language. I still do, after having learned C# (which is comparable to Java at any scale and comes as a close second on my list of favorites), PHP and a bit of VB.NET ASPX, and Ruby. Then, I got into mobile (Java Android), and it got even better. I loved the Android Java even more then Java itself (here however I may be in the dark, as I have no experience with other mobile development frameworks). Once I learned the API basics and guidelines, it was all breeze and fifth gear (it was an internal applications targeted to tablets. The purpose was to give the delivery boys and drivers a means to keep track of where they go, what they pick up and what they deliver to customers). Lately I've been mostly caught with C#, building modules for an Oracle ERP automation. While has been, and still is fun, and while I really like what I'm doing at the moment (to me, LINQ does rule btw), I miss Java. C# and VS to me seem too, dunno, businesslike, while Java (both under NetBeans and Eclipse) seemed a little more leaned back. I'm not hardcore fanboy enough to say it has no shortcomings (and I won't even go into details here). Not at all, but then which language doesn't? All in all, I can't even put my finger on why I love Java. I just do. Personal preference maybe, but it's mine and I'm keeping to it. EDIT: I'm not using it for everything and I don't say that it's good for everything, AT ALL! There are languages far better suited for certain tasks (.NET for Windows-targeted development comes to mind). But having to choose between Java and another language equally suited for the task at hand, I'll always choose Java.

Microsoft had Java under Windows and then Visual J++. Sun sued them saying they own Java and Microsoft had no business improving on it with J++. Microsoft told Sun to elephant itself and came up wih C#. That is why C# is comparable to Java.

I knew that (although I was under the impression that the name would actually be J#), and as far as I remember, Sun sued under the reason that MS's implementation didn't respect certain clauses in the license. However, the reasons are less important. The two are really close to syntax and usability / learning curve, and that's what made me like C#

The thing is that Java provides the shells needed to use Java/run Java apps on any platform. DotNET doesn't provide such shells (mono, for example, is third party open-source), so you can't simply copy a DotNET program to a mac or Linux machine and just run it without jumping through several hoops. The biggest problem with Java was performance, which was easy to hold up and sneer at, so, now that its performance has been hugely improved, people are getting antsy, and publishing scare stories that will just make Java supporters turn even more hard core.

Versus what and in what context? Having spent 15 years (or longer?) writing servers the performance problems I have encountered have been due to requirements, architecture and design. And none of those have anything to do with language. And given that I have been doing java and C# for years and spent many years in C++ I do have some experience in those languages. And excluding some very specific problem domains I have never read anything that suggested that my experience is atypical - most performance problems are related to things beside language.

Absolutely no evidence of that. Looks to be as popular as ever. Note of course that C is still popular too. http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html[^]

Myself I implement business functionality which involves servers and the performance bottlenecks from them are always related to requirements, architecture and design. One can achieve orders of magnitude of performance by adjusting those. One can't do that by language choice (based of course on standard business languages and general business domains.) Of course trivial language benchmarks have nothing to do with performance in large enterprise systems. And in case there is any confusion I spent more than decade working in C++ including extensive measured profiling of applications written in it.

I have worked in many languages including java, C++ and C#. And worked at many companies. There was exactly one company that had a real reason for choosing the language that they did. And that choice had nothing to do with technical merit but was instead based on a marketing decision (and a reasonable one at that.) Doesn't mean that I haven't been told many times that a certain language was choosen for technical reasons. But the reasons always really resolved down to subjective preferences.

Until Java 1.5 & 1.6, Java was a snail, compared with C++, for example. There are tons of sites that show benchmarks. A good upshot of that is that it encouraged people to spend more effort on optimising code.

IDENTIFICATION DIVISION.
PROGRAM_ID. WHAT A BORING LOAD OF ELEPHANT DROPPINGS.
AUTHOR. A POTENTIAL SUICIDE.Almost fun, wasn't it? ;)
One of these days I'm going to think of a really clever signature.
Not bad for the times and for the tasks it was designed for. I don't think I ever put anything in IDENTIFICATION DIVISION except the PROGRAM-ID. The idea that in the CONFIGURATION DIVISION, you could specify source and target computers was an idea before its time. Even for today. Unless there were cross-compilers for every computer on every make of computers, that was useless. By the way, I always thought RPG stood for READ, PRINT, GO BACK; a throwback to its derivation from the wired-program accounting machines such as the IBM 407. :laugh: Some salesman named it Report Program Generator and people bought into that!

More importantly most job postings are for java (excluding an odd uptick in C) and that hasn't changed much for many years. http://www.tiobe.com/index.php/content/paperinfo/tpci/index.html[^]
Most in demand or hardest to find resources? There is a difference...

Where was dotNet in 1998? Ever hear of MS Java or J-sharp?
Basic history:
MS saw popularity of Java rising.
MS products at the time were VB or else VS C++/MFC
MS tried the embrace, extend, extinguish recipe with Java 1.1,
but Sun sued them over changes and additions MS added to Java
MS stopped their Java implementations at 1.1 as part of a settlement and
agreed to support Sun's applet plugins better in IE.
MS still saw the benefit of the technology, so they switched all of their
Java/VM efforts into dotNET/C# to directly compete with Java.
Look at the original dotNET APIs vs. Java APIs at the time. 1:1 correlation.
Meanwhile, Sun had become too content with the Java 1.2 spec. They thought they
were done!
dotNET caught up to Java and passed it up in terms of functionality.
Sun grudgingly started adding things like generics and enums which they originally
said they would NEVER add.
Thank goodness for the competition or Java 1.2 might have been the last Java version!Reasons for using Java:
It was the best choice in 1998, 1999, etc.
Many Java tools have had hot code replace since 1999. (Huge time savings!)
It is still a good choice today. (Still best for our product)
It is so universal, that there is TONS of free, open Java source out there.
It is multiplatform. (Yes. with no recompilation, it runs on Windows, Mac, Linux)
It was and still is browser deployable.
Silverlight apps are just Java Applets reworked. (Admit it!)
Java Applets will keep working,
but it looks like MS is already trying to kill Silverlight.
Browser deployments of Java can still provide more consistent behavior
cross browser than JavaScript/HTML5.
Java+Eclipse allows for 25,000+ source file recompiles in 10 minutes,
of course, good incremental compiling is
normally subsecond to compile and hot replace
true databases of workspaces/solutions, etc. As far as I can tell,
VS looks like it still scans files for references.
It has been really stable. Code compiled against Java 1.2 12 years ago should still
run fine with 1.7.
If you adopted (and reworked your app) each time MS technology
for database access has changed, how many times would you have done this?NOTE: You should never let any untrusted site run ActiveX, Java, JavaScript, etc. in your browser, EVER! Why did Microsoft have to add the ActiveX kill bits, etc

At least .NET doesn't scream at you "I want to update" every hour on the hour. Or at least it seemed to whenever I had the JVM installed. Don't anymore, and avoid anything that wants it.

Actually there are some enterprise frameworks in Java. In general, they are huge structures, used for big projects, with extreme emphasis on modularity and design patterns. So you don't actually "choose" to do Java: it has been already decided for you in the structure maintaining those systems. You can find a lot of that in telecommunications and public institutions. On the other hand, I've seen very few new projects actually being done in Java. Despite the strengths of the community, Java as a language has remained behind the times (the language itself has nothing like dynamic types, LINQ, functions, type inference or async, which make in most cases half of the design patterns obsolete or transparent) and ends up requiring double the code for most tasks. By the time Java 8 will be adopted for real projects (ie all your components will have updated their API etc), it will have become a dinosaur, like COBOL. It's actually in free fall in the Tiobe Index[^].
