Java vs .NET 686

CHaN_316 writes "Yahoo is running a story called 'Is Java Finished?' It provides a brief overview of the strengths and weaknesses of J2EE and contrasts them with .NET. Classic arguments are brought up like Java being great for portability while .NET ties you down to Microsoft products, etc. It's interesting that they bring up the Java Community Process, and how it is a rather slow moving procedure that is causing Java to become stagnant."

    The Software Development Times ran an article [sdtimes.com] which mentioned many of the perceived advantages of .NET, and Kuro5hin ran a story which did just the opposite [kuro5hin.org]. :)

    Dot Net doesn't look like a developer panacea just yet. If Sun keeps the enhancements coming and works to bring the development environment up to Visual Studio's standards (Yes, VS has its problems, but it has a lot of unique tools, like compile-and-continue, which save hours!), Java may well survive.

    Dot Net is also anything but small. It's possible to create ROMmable Java applications in just a couple megs of flash memory. On the other hand, there's no such thing as embedded dot Net just yet. And if they continue with the execution model they've currently got, any piece of code is going to net a ROM many times larger than what's possible with Java. Either way, I'll want $699 for my fp, beeyotch.

        This isn't always true. I am a developer for a fortune 500 company and we just finished a huge Java vs .Net comparison. The company brought in a lot of outside opinions and had us devlopers give opinions as well. Of course an MS rep was there telling the tall tales to all the PHB's of how .Net would make us 10x more productive and save us millions (just like the commercials), though the figures did not include all upgrade costs for Win2003 Server and WinXP cost. When it was all said and done, just about everyone picked Java, except for the MS rep and a few VB/ASP only type guys who don't have the technical ability to program much more then a few asp pages. It all came down to Java is proven to be stable and secure. MS and their technologies have not and especially .Net. We also have many mission critical apps that just cannot be trusted on an MS platform so they run mostly on Solaris and now some Linux boxen are popping up. Java gives us the ability to choose the right tool for the right job. .Net would have locked us in to just MS and severly limited choices. Once we as developers got that point across to the PHB's, they were able to see the light.

      One thing with the SD Times identified as a source of trouble (the size of the included libraries), I identified as a strength: .NET has a lot of things "in the box" that a developer / team needs to go find, select, download, install, etc. for Java. I personally like the best-of-breed approach that can result from that (choose from the many SOAP implementation, choose the best one for our needs), but for many developers, having a good-enough solution "in the box" is more palatable.

      This is particularly exacerbated in some development shops where extensive format decision and permission processes are needed to make any third party tool purchase (or free software adoption).

      I wouldn't say that .Net will never take off. Microsoft has access to senior executives in large corporations; I know that shouldn't make a difference, but it does. I am consulting at a major communications company now, and I just got a call from a VP an hour ago saying "Take a look at Microsoft for the stuff you are doing." It seems MS paid him a visit, and they are pitching lots of .Net/XP stuff against our existing HP SuperDome environments.

      Think of this another way: What if .Net was designed by a single person in their garage, would it get the attention it does? Of course not. Dot Net is a real threat to Java simply because it comes from Microsoft (a mega-corp with plenty of access).

      You may not like it (I know I don't), but that is the nature of things.

      After all, it hasn't during the 3 years its been out.

      Technically .NET wasn't released until a year ago last spring. It's only been out about 18 months. Last fall it was clear that people using .NET were very early adopters, but uptake seems very strong.

      To be honest, Java on embedded devices doesn't seem like that big a win to me at the moment, no matter how many cellphones they're trying to ship with it. Most Java in use is on the server side. And that is a big differentiator between Java and .NET: Java runs on pretty much any hardware you care to throw at it, which means you can scale your server from that itty-bitty Pentium box up to the biggest stuff Sun sells. With Windows you've got midrange Intel boxes and ... midrange Intel boxes. Little per-box scalability, and that means that large systems are going to be a pain to manage - particularly given how hard it is to manage Windows servers in bulk.

      I can see .NET being useful for small servers that need to be put together quickly and cheaply; VS.NET is great for that. But it's not really there yet for big systems, both in terms of framework maturity and OS scalability and stability.

      Mostly I think we'll see .NET be used in building GUI applications in the near term. Let there be no mistake, it is phenomenal at that.

I work for a large California Bank and our on-line banking software is written using Java servlets, Java Server Pages, and Enterprise Java Beans. We connect to an Oracle database via JDBC. As you can see we're very Java-centric

      The thing that really helps us is that we can develop code using WSAD (WebSphere Studio) on our Windows 2000 boxes on our desktop. We then deploy to a development sandbox made up of several Linux boxes (Same code, no recompile). Once we test it there we port it to our Development Test box which runs on IBM's AIX operating system (as do the test, stress test, and production servers).

      Could we pass our code around to multiple machines with 3 different operating systems using .NET? No way. Could we toss a WebSphere server on a cheap Linux box and have a test bed up and running in an afternoon? Absolutly, Could we do the same thing with a Windows 2000 server? Not if we want to expect the same level of performance (both speed and stability) out of the same hardware. And that doesn't begin to worry about the licensing cost of building that quick and dirty test bed with Linux and Java as opposed to Windows 2000 and .NET

    This John Rymer guy, around whom this entire article is based, is talking out of his arse. When will journalists learn that if you want to know something about software engineering, ask a software engineer? Only PHBs, clueless journalists, and other analysts listen to analysts.
    Java and .NET take vastly different approaches to development, said John Rymer, a vice president with Forrester Research. Java's philosophy of development is to expose low-level system interfaces to give developers greater control. Microsoft simplifies the development process; the developer has less control -- but the tools are easier to use.
    If anything, the opposite is true - the Java API is certainly higher-level when it comes to GUI stuff, and everything else is pretty analogous between the Java and .NET APIs.
    "Before, Microsoft was basically shut out of these projects," Rymer said. .NETs ease of use and lower licensing costs also will be a draw.
    Lower licensing costs than free [jboss.org]? I would love to see that.

    Having worked with both Java and .NET, I would say that things like C#'s foreach statement make for easier and cleaner code, but Java 1.5 will leapfrog C# when it introduces generics along with its own version of foreach, and other timesaving features.

    Java originally promised to become a small, universal client-side platform for the delivery of applications to clients over the web. Java has almost completely failed in that mission: Flash is far more widely used, no browsers ship with the latest version of Java, and even if you stick to Java 1.1, there are numerous compatibility problems.

    What Java has become instead is a semi-open server-side platform. It's quite successful at that, but it is only one of many platforms in that space. PHP, Perl, Python, and .NET will continue to exist in that space as well and probably take away market share. And because Sun's restrictive licenses on both the implementation and the specification of Java, I suspect Java has seen its best days in the open source world.

    Now, about .NET, .NET is simply more of what Microsoft has always given us: a proprietary platform completely controlled by Microsoft. It's not primarily an alternative to Java, it's simply what Microsoft programmers will move to from MFC and Win32. Thankfully, it's at least a lot cleaner than Microsoft's previous APIs and systems.

    So, Java has failed to become what it originally promised to become, but it is a fairly successful platform that won't disappear overnight. But Sun's dreams of industry domination are pipe dreams. Java could have become much bigger and more important than it has become, but Sun screwed up (and is continuing to screw up).

    From the article,
    .NET's ease-of-use characteristics are forcing Sun to try to simplify Java development.

    and later,
    Sun needs to make the Java Community Process (JCP) more efficient and simple, because its unwieldiness is slowing the adoption of Java standards

    Huh? So first this article complains that Java is too complicated and needs to be simpler. Then it complains that Sun makes it hard to add new features (i.e. complexity) to the platform.

    I'll say it again...Huh?!?

    I think the JCP moves at just the right speed. If you change a language too quickly, make it harder for everyone to keep up. If you move to slowly, the language/platform won't be able to keep up with current technology. It should be hard to add things to the Java platform. A lot of people have a lot of different ideas about what Java should be. Sun tries to make sure only the best of the best gets integrated into the core platform. Anything else can be left as a 3rd party library (like AspectJ for example).

    A great man once said, "The Law should be stable but never stand still". Programming languages and platforms are the same way. Turning the JCP into a rubber stamp for new, unproven ideas isn't going to do anyone any good.

    I don't believe Java (by which I mean the entire Java 2 platform, not just the language) is "finished" as a commercial platform, but I think it is finished as an open source platform unless Sun makes some radical changes. Why?
    • Maintaining WORA and interoperability among implementations is the stated goal of Java, and Sun has put teeth into their licenses to try and enforce that. That is, even the Java specification is covered by a license that prohibits you from releasing your own non-conforming version. While that may or may not be a laudable goal, it is in conflict with the fundamental principles of open source that you can take stuff, improve it, and release the improved version. And I think it actually is harming the technical development of Java.

      Another way of looking at it is that Java is too encumbered by intellectual property--copyrights, patents, and licenses--held in part by Sun and in part by an industry consortium (JCP). Anybody that builds applications on top of Java becomes as dependent on Sun as people who write Windows software become dependent on Microsoft. While there are plenty of open source projects for both Java and Windows, ultimately, that is not a good state of affairs for open source developers.

    • WORA brings with it a lot of costs but few benefits for Linux developers. When I write a Linux desktop application, I want it to work well on Linux, I don't care about whether it runs on Windows. But if I use Java, there are all sorts of Linux desktop and Linux kernel features I can't access. And the entire design of Swing and Java2D is based on a Windows/Mac-like local display model, something that simply does not work well with X11.

      WORA made sense for Java's original purpose in life, that of a thin, universal client platform. WORA makes no sense for Linux developers trying to develop high-quality Linux applications. (And, frankly, I think Windows programmers are saying the same about Java on Windows, which is why .NET will probably be more popular with Windows developers).

    • Java is just not a very convenient language to program in. For most needs, something like Python, Perl, PHP, or Ruby is simpler. And when those are not powerful enough, people just drop into C/C++ anyway.

    Java held a lot of promise for open source development at one point, but I think that's over now. The Java platform will continue to be used widely in many commercial (and some free) server-side applications. Subsets of Java will be used in teaching and research. And you will see more and more partial clones of Java appearaing. Open source will probably continue with a mix of languages. gcj+SWT, which implements the Java language but not the Sun APIs, may achieve modest popularity. Mono+Gtk# may become fairly popular (but the .NET clone that is part of Mono probably won't--both for legal and technical reasons).

      Yeah, except that some people actually just, *gasp*, *like* to program in Java. It provides a nice, strongly typed, compiled, object oriented language (a niche none of those scripting languages fill) that's available almost anywhere while being FAR nicer to develop in than either C (too low-level and error-prone) or C++ (to damned friggin' ugly).

      Moreover, Java provides a massive class library which makes it easy to write new applications without having to reinvent the wheel every time (and yes, I know about the STL, but it's still not entirely standard, it creates bloody HUGE application binaries, it takes FOREVER to compile, it's *impossible* to debug compile errors, and it isn't even as extensive as the Java APIs!)

      Now, I would agree that Java is pretty well toast on the desktop, barring a toolkit revolution. I certainly wouldn't write an app using Swing. However, for other types of applications (like, say, Freenet), it can do an excellent job. And if you go with SWT, you can write some pretty damn nice GUI apps (just look at Eclipse, which is written entirely in Java).

      But to dismiss Java out of hand because it doesn't mesh with your and some other zealots ideals is pretty narrow minded. Personally, I don't care if my app is somehow "tied" to Sun. As long as I can release my source code, who gives a damn if it runs on a proprietary substrate. That certainly didn't bother the KDE guys (or their users) back when Qt was non-free. Sure, there were people who complained, but there were also plenty of people who didn't give a damn (myself included).

    Java's philosophy of development is to expose low-level system interfaces to give developers greater control. Microsoft simplifies the development process; the developer has less control -- but the tools are easier to use.

    Says who?

    I've developed applications in both .NET and Java and I've found Java's toolset to be much easier to use. This is simply due to the fact that there are many more vendors (open-source and commercial) that provide Java products. I can pick and choose which tools fit the particular project that I'm working on, and those tools will also run on any platform that Java runs on, so I'm not locked into a particular operating system while I'm doing development. I can decide to work in Linux one day and Windows the next, and use the exact same toolset for both.

    So I guess if your definition of simple is "you will use this tool and like it", then yeah, .NET is simpler. But in that case I'll take complicated over simple any day of the week.

    I think this was really nice, and fitted in well with Microsoft's COM framework. I remember COM enthusiasts mentioning how every C# object would automatically be a COM object, thereby eliminating all that old school drudgery.

    C# is the first language to incorporate XML comment tags that can be used by the compiler to generate readable documentation directly from source code.

    Java versus .NET is becoming a ubiquitous topic. It's been the subject of debate since .NET beta 1. Microsoft and Sun both have "independent" studies conducted to prove that their platform (J2EE/.NET) is better and both have convincing arguments. There is no perfect language or platform to solve every programming problem - sometimes it's C++, sometimes it's Python, sometimes it's something else - it really depends on the problem.


    It's no secret that one reason Microsoft created C# is to compete directly with Java. It's pure ignorance to say that C# is proprietary and that you're locked-in to Windows. C# and the CLI (.NET) is an approved ECMA standard [ecma-international.org]. This is something SUN was unwilling to do with Java. For this reason, in a sense, Java remains far more proprietary than C#. It's too early in C#'s life to say that it won't be ported to other platforms - look at Mono [go-mono.com]. There is a lot of FUD being disseminated about "Microsof is going to sue Ximian, et al. for Mono" blah,blah,blah. That's not going to happen. Microsoft has already released the source code to the CLI [microsoft.com] with one intention of "People developing their own CLI implementations will find the Shared Source CLI an indispensable guide and adjunct to the ECMA standards.". So, for the argument that C# and the CLI are proprietary and one is bound to Windows is just plain ridiculous.

    Syntactically, C# and Java are extremely similar. They both derive from C++. Structurally, they are very similar as well. They are both OO languages, everything is a class, etc. Side-by-side they look very similar. There are numerous small details which make C# "friendlier" than Java, ie. C# has no requirement that the file be named after the class. However, C# has a lot of other advantages over Java. C# can make use of pointers. Java has no option on parameter passing - Objects are passed by reference, value types are passed by value. While C# has the same limit on objects, you are able to use pointers and it also supports boxing. C# supports operator overloading as well. On the merits of the languages alone, C# is stronger than Java. It should be expected since it was developed from scratch nearly 7 years after Java arrived.

    As far as performance, Java leaves a lot to be desired. I won't belabor this issue. If you'd like a demonstration of the difference between the run-time execution of .NET vs Java, pick your favorite VM and run Forte, then run Visual Studio .NET (it's written in C#) and decide for yourself. Java run-time performance alone is enough to dissuade some developers.

    Java does come as close to a RAD language as can be. Java applications can be developed quickly with far fewer bugs and errors as a comparable C/C++ application with the benefit of garbage collection as well. For this Java gets an "A". It greatly simplifies the process of rapidly developing database and other applications.

    Is Java going away? Hardly. But like it or not, C# and the CLI are here to stay as well. It's only a matter of time before the CLI is ported to other platforms and environments just like the JVM.

      Your omniscience is impressive.

      Microsoft has gotten EMCA's stamp on C#, the CLR, and the basic Framework, but they still control them with an iron grip. When .NET's behaviour differs from the ECMA spec, who's right, ECMA or Microsoft? Who gets to decide how things will evolve --- ECMA, or Microsoft? And of course .NET is much more than what ECMA has blessed. I doubt we'll see ADO, ASP.NET, System.Windows.Forms or a bazillion other APIs that you need to write actually useful applications in ECMA anytime soon.

      Even if you're willing to go beyond ECMA and port the Microsoft proprietary APIs to other platforms, the fact is that System.Windows.Forms is absolutely NOT a cross-platform GUI toolkit. The Mono guys are implementing it by sucking in WINE! There is simply no Microsoft-blessed cross platform GUI toolkit for .NET.

      You mention three advantages there:
      - pointer support
      - boxing
      - operator overloading

      I'm sorry, but in the average commercial environment, churning out business logic to meet changing business requirements under tight deadlines, two of those three are very very bad.

      Boxing is good. That's probably why it's in Java 1.5. I'd have liked to see it in 1.1, but that's another discussion.

      Pointer handling: I've written code doing direct memory access via pointers. I've also written code in Java (and thus not had access to pointers). The Java code has been at least as easy to write, had far fewer bugs (invalid pointers? memory leaks? not in my code), and (most importantly) been immeasurably easier to maintain. You might have been programming for 20 years and never have a problem with pointers; most developers have been programming for 2-3 years, don't have a sodding clue about pointers, and will and do screw it up. Quite frankly, pointers are evil and unnecessary and if I do use C# in the future (as is likely) I'll be insisting on coding guidelines that preclude their use.

      As for operator overloading: It's one of those things that makes C++ code so bloody impossible to maintain. Bit of code read x += y. Except it's doing a binary concatenation, or advancing the pointer reference, or updating Z instead. Because some idiot has overridden +=.

      I appreciate that there are situations where operator overloading is useful, even some where it's sensible. Unfortunately, going back to the average developer: They don't know when to use these things, and even if they do, they often don't know how.

      I love Java not because I'm a crap programmer (although I wont deny that) but because it makes my life much much easier. I can write code quicker, more efficiently, and more robustly. I can maintain code extremely easily, as the 'gotchas' that exist in many languages just aren't there in Java. And my boss loves the fact that he's getting new functionality so much quicker, because the whole team isn't spending their lives debugging a complex overloaded operator that's invalidated a pointer.

      I'm not saying C# is a bad language. I am saying that operator overloading and direct memory access (through pointers) is unnecessary and evil in the average corporate development environment. And that's the target environment for .Net.

I have run into many shops that love using Java on the server side and also love using truly native GUIs on the Windows desktops. Using the right tools, you can easily do that.

    My favorite tool for the integration is JuggerNET [codemesh.com], which transparently starts up a JVM in the CLR process and the developer simply codes against generated .NET classes. I am affiliated with Codemesh, so I'm somewhat biased (take a look at Stu Halloway's great website [develop.com] for alternatives) but working with both platforms for a living, I just can't get excited about controversial this or that is dying statements. Both platforms have their strong and their weak points.

    I love the platform portability of Java, but I think Java is too closed in terns of language integration. Doing JNI by hand is an abomination, and most people at Sun admit it.

    I love the language portability of .NET (it's not perfect, but then, neither is Java's platform portability) but I hate the exception model.

Put it together with Apache Open Source products such as Tomcat & Apache httpd, or JBoss if you are into EJBs and you can't go wrong.

Thus, all things equal I'd bet most businesses will probably opt for a Java (or J2EE)/Linux solution as the overall price can't be beat, and you don't have to waste you development time creating valueless libraries that others must have had to create already.
