I dont get it, after all of the criticism's and misconceptions Java recieves, it is still the most in demand Programming Language for Programming Jobs. Why is this?I mean, there have been literally thousands of article on how Java is "slow","bloated" etc, yet it seems to be a hugely popular language in the Programming jobs world,my question is, why?
The first and the basic things with Java is Platform independent and so this is becoming more and more popular.
Also we neednt wirte lines and lines of codes.. we can use the existing inbuilt methods..
Yeah, portability is a great issue for many software companies, they dont have any other good option. Java just fits perfectly there.
There are thousands (probably millions) of mails/articles against Microsoft OS platforms. Countless viruses , worms etc. using Windows vulnerabilities to harass hapless users. You have to pay for MS -development platforms and sometimes runtimes too (unlike Java SDK and many Java IDE's and web tech. containers which are free). even then more than 90% desktops have MS-Windows OS why ??Quote:

Java is probably the only viable language as well as technology platform outside MS today and most of it is free :) and whats more its portable (means runs on non MS OS too) and whats more oftentimes the execution speed is pretty good.
Agreed. Its portability and its stability are what win it with me, and I used to be a big C++ fan.

Early versions of Java were relatively slow compared to C/C++ because the runtime translation to native code was inefficient. The detractors jumped on this and some still use it. Meanwhile, Java technology has advanced and performance is no longer significantly poorer than alternatives. I don't recall any claims that Java is/was 'bloated' - perhaps you could refresh my memory? A language is only a tool to perform a task, and a sensible developer will pick the tool best suited to the task (within the external constraints imposed). Java addressed a problem domain that was poorly supported by the tools previously available, and was simpler and easier to use. Interestingly, Microsoft has now adopted a Java-like architecture with .NET, and has extended and surpassed it within the limited context of MS operating systems. Java continues to be the most popular tool for platform-independent development, particularly web and multi-tier applications, because it is now relatively mature and stable, it's simple, effective, and easy to use, has a wide range of high-quality libraries, an active and open support network, and doesn't suffer the single-supplier dependencies of MS offerings, etc., etc.Quote:

A most important, but also most elusive, aspect of any tool is its influence on the habits of those who train themselves in its use. If the tool is a programming language this influence is, whether we like it or not, an influence on our thinking habits.... A programming language is a tool that has profound influence on our thinking habits...

Very true! Look how much critism Microsoft gets, but people still use it.Quote:

The negative articles about Java you mention are mostly from before 2003 when they were true. Today Java can compete successfully with other languages in some application areas but one shouldn't forget that it has been seriously crappy until quite recently.
It probably will take another 5 to 10 years until Java has gained the full confidence of most mainstream developers. One thing that would help would be if Sun finally got its act together and proved beyond reasonable doubt that Java programs now are fast than their statically compiled counterparts. Not that it matters much but it would boost credibility and lessen the hype-deficit built up during Javas early years.
I did see a comparison of Java with C++ a couple of years ago that showed (given a good JIT compiler) that in many situations it was as fast as C++ and sometimes faster... The problem with this kind of comparison is that there are so many disputable variables - environment, compiler, coding style, application, memory, timing, etc., etc. It's comparing apples with oranges, they are different tools suited to different purposes, and "my language is faster than yours" head-butting is really just ego massage. It may raise publicity-generating controversy, but anyone who takes such a superficial approach to their selection of language tools is unlikely to be able to take good advantage of whichever one they choose in any case...Quote:

The speed of a non-working program is irrelevant...

I have worked on some major webbased application on J2EE platforms before 2002. At that time some app servers were not very good in speed even then the application that we developed was much faster (in terms of execution speed) compared to the VB/VC++ applications which were replaced by our app.
Now this may have been do to better design on new app or bad design for legacy apps. , but the bottomline was it executed faster and was easier to maintain and was done in Java.
I think the burden of proof rests on Sun. Right from the start in 1995 the implicit promise was always that a dynamic runtime system (represented by Java) will eventually overtake a static one (represented by say C++) in speed. The main argument being that a dynamic compiler has runtime information available which would result in superior optimizations.Quote:

I don't really follow your argument. How can another language 'hurt' C++? Has the SPCC (Society for the Prevention of Cruelty to C++) complained?Quote:

Then you use the one that performs best. There's no burden on Sun to prove anything - Java is much faster than when it started, and it's entirely up to you whether you use it or not. If it will do what you want, fine. If there's a better solution, use it. If you use hype to guide your choices you deserve everthing you get.
In my experience, most developers and developments that moved from C++ to Java did so not because they believed some hype that it would be faster, but because it was new, interesting, easier to use, and more suitable for the emerging web applications and client-server systems.
Simplicity and flexibility will trump optimization and power in a world where connectivity is the key...

Languages compete. Do you really think Sun could afford to let Java fail? How to prevent that? Hyping Java and badmouthing C++ of course, backed by an enourmous amount of company cash.Quote:

Just out of interest, what did Sun claim that they haven't delivered and which 'hurt' C++ (a reference would help - I believe all Sun's public statements are online) ?Quote:

Anon.
Why are you so formal? I've lived through this from the birth of Java and onwards. The true story is never in public statements and you should know that if you are a practitioner.Quote:

You claimed that Sun overhyped Java and dissed C++; I spent years developing with C++ and moved to Java as it became mainstream, and I don't remember the sort of hype from Sun that you claim, so I was curious about what they'd actually said (although I do remember plenty of 'my language is better than your language' wars between developers who should have known better). As I suspected, you can't or won't back up your assertions, so I can't take them seriously. Most businesses make exaggerated or over-optimistic claims about new products (remember 'The Last One' ?). Sun and Microsoft are no different and anyone with any commonsense takes it with a large pinch of salt.Quote:

A programming language is a system of notation for describing computations. A useful programming language must therefore be suited for both description(i.e., for human writers and readers of programs) and for computation (i.e., for efficient implementation on computers). But human beings and computers are so different that it is difficult to find notational devices that are well suited to the capabilities of both.
