101 Reasons Why Java is Better than .NET (Reloaded)
The original edition was put together using a blogging system, this edition
is now based on a Wiki system. Hopefully, the comments and contributions will be
richer this time.
The list is structured such that all 101 entries can be viewed on a single
page (unlike the original!). Each entry would be accompanied by a "sound bite"
that bests captures the intent of the entry (if you got a good one, please let
me know!). Each entry is also a link that you can navigate to examine more
details and supporting information. At this time there is no particularly reason
for the ordering and that will change at a later date (so please don't cite the
entries number when you make an external comment!).
For an easy to remember url to link to this list and all future editions use
101.manageability.org . Feel free to post this url in response to articles and
posts falsely promoting the benefits of .NET.
Finally, for those who unfortunately have legacy .NET deployments, here a
series of articles that will help you migrate to a superior Java platform .
Public Domain APIs - Any Java public apis are part of the public domain,
.NET apis are proprietary and can open the door to a law suit.
Standard Library Source Code Availability - Java source code for the core
libraries are available in every J2SDK distribution, .NET sources can only be
seen by resorting to illegal means.
dotNet Purity Is A Myth - Java promotes 100% pure Java libraries, for .NET
purity is nothing more than a myth.
75% Of Enterprise Software Development - Avoid becoming one of the 25% of
"use-less" employees.
Preferred Platform for Implementing WebServices - Despite billions spent
by Microsoft in marketing, surveys continue to reveal that Java is the
preferred platform when it comes to Web Services.
Superior Platform for Web Development - ASP.NET is a poorly designed and
crippled framework as compared to the richness of frameworks found in Java.
Write Stored Procedures using Java - Most relational databases support
writing of stored procedures in the Java language. There has yet to be a
production release of a database that supports any .NET languages.
An Abundance of Experienced Practitioners - Nobody seems to know how to
write .NET programs well and that's giving .NET a bad name! A pretty lame
excuse I must say!
Supportive Open Source Communities - Open Source communities that support
distributed development are a plenty in the Java world.
Proven Security - 2 Years after Trust Worthy initiative is launched and we
collectively lose $55 billion last year.
No Lizard Brain - .NET programmers continue to struggle with the
complexities of a hybrid managed/unmanaged environment.
More Languages - The JVM is more "common" than the CLR.
Smaller Runtime Download - You can't run your app if you don't have the
runtime.
No Mandatory Upgrade Fees - 3 things a Microsoft shop can't avoid: Death,
Taxes and License 6.
More Vendor Choices - .Net is a marketing program. Java is a Market.
Industrial Strength Collection Classes - The .Net libraries look like they
were designed by high-school students, First year CompSci? students at best.
FutureProof - The way to ensure your return on investment (i.e. ROI) is
that your choice of platform doesn't get obsolete in 5 or even 10 years. Avoid
the Microsoft upgrade treadmill!
Larger Talent Pool - Majority of Universities not only teach but require
knowledge of Java. That's a big talent pool that you need to consider before
you off-shore your project to a different time-zone.
More Contributions From Researchers - Research institutions and
universities have consistently provided innovative research not only built on
top of Java but also contributing to Java.
US Government Approved - Guess where the billions of dollars spent on the
U.S. government's IT renovation is going to?
NoEvilTypeCoercion - Some C++ constructs are meant to be entombed forever,
.NET resurrects them with disastrous consquences.
More Mature And Robust O/R Mapping - You can't beat the wealth of O/R
mapping solutions found in Java.
Superior Coding Tools - Like having your own personal Java fairy dancing
through your code, anticipating your every thought and keystroke.
Sane Coding Conventions - I don't know what's worse Hungarian notation or
.NET coding conventions.
Higher Paying Jobs - Somehow you've got to afford those skyrocketing
housing prices don't you?
Favored for Implementing P2P - Gnutella and JXTA, anything else legally
more pervasive?
PureJavaRDMS - Can't beat the ease of installation when the RDMS is Java
based and packaged with the application in a .zip file.
More Exception Handling Options - .NET has no analog to the throws clause
in method signatures.
Better Structured Diagramming Frameworks - When going beyond forms and
windows, Java can't be beat.
Reusable Open Source IDE Frameworks - Why re-invent the wheel? Start
building your killer GUI application on top of killer IDE frameworks.
RobustParserGenerators - Want to build a new language, well you'll need
some robust parser building tools.
AspectOrientedProgramming - The next advance in modular software
development, get a head start by using Java.
PureJavaWebServers - Customizations and extensions are easier in a web
container that's built using the same language as applications. Furthermore,
managed environments support better reliability and security.
OpenSourceJavaCompilers - Your tools have got to be able to parse the code
before it has any chance in understanding it.
Distributed Caching - Sometimes embarassingly parallel applications aren't
the only things that you need to scale.
MultipleReliableMessagingChoices - Java provides more choices for the
backbone that integrates the Enterprise.
Faster Development Turnaround - Incremental compilation is unavailable in
the .NET environment.
Lightweight Persistence - Sometimes a relational database (RDMS) has too
big a footprint.
Open Community Process - How does one contribute to the specification of
standards?
Hardware Accelerators - Performance boosting hardware.
More Flexible Licensing Options - Ultimate flexibility in licensing.
EmbeddedDevices - Java inside small packages.
Faster Virtual Machines -
MickrokernelArchitectures
ContinuousBuild

F7.
Embarassingly Rich Information Sources
More Open Source Projects
Affordable Industrial Grade IDEs
Standardized Enterprise Connectivity
DynamicLanguagesSupport
MorePDASupport - Why limit oneself to a single PDA brand?
OpenTechnologyRoadmap - .NET is like a five year plan in the former USSR:
You know it doesn't actually make sense or help anything, but if you live
under it, you're certainly not going to say anything negative about it.
EmergingStandardsSupport
JavaCard - JavaCards? are becomming the preferred method of keeping tabs
on your citizenry or customers. If Microsoft ever co-opts this technology then
"1984" will become more than just a paperback novel.
Complete Open Source Stack - Open Source code visibility spanning all
layers of an application.
NonStopServers - .NET not fault-tolerant enough for
Hewlett-Packard-Compaq?

of show stopping bugs.
Eclipse
OneHunderedReasons
1 comment:
1. .NET is ECMA/ISO standard so the APIs are public
2. Microsoft has an implementation called ROTOR (aka SSCLI) which has the source code
3. Mono does an implementation of .NET on *NIX, what purity?
4. Microsoft focusses on Windows implementation and many enterprise have UNIX hence mostly Java
5. Same as previous point.. because Server run UNIX historically, web services are implemented in Java. In fact SUN had refused to be part of webservice standard initially promoting ebXml instead
6. ASP.NET vs. JSP... Take a relook at development times..Framework is fine, where are the tools for JSP developement? Eclipse?
7. SQL 2005, Oracle 10.2g and IBM DB/2..ALL of them support .NET data types in their DB
8. I think you need to re-check .NET expertise availability. My experience is completely different
9. open source has been favourable to Java as open source and java both have been anti-MS. but there are NUnit, Nant, NDoc, NHibernate, Spring.NET etc for .NET too
10. Heard of CAS in .NET?
11. Most teams dont require managed/unmanaged and its simpler than JNI for sure
12. .NET supports 20 languages, what does JVM support (officially 1 - Java)
13. .NET runtime is smiliar size as JVM and its bundled in WinXP SP and Vista, so no download required
14. .NET framework is free.
15. MS, Mono, Portable.NET
16. Industrial strength Libraries.. whose opinion is that?
17. Upgrade? are we talking about .NET or MS now? .NET upgrades are free. .NET 2.0/3.0 work on WinXP
18. Talent pool is based on market requiement. Java is 10 years old, .NET is 5
19. Look at some reasearch from Eiffel, Haskell, Python teams
20. No idea about US govt approve. ANyways I dont take permission from US govt before i write either Java or .NET apps
21. If i remember correctly, the C++ constructs Java threw out are back.. like enums, attributes in Java 5???
22. No opinion on O/R mapping even though there is nHibernat
23. Superior coding tool? eclipse? lets eclipse first do a JSP or Swing based WYSIWYG
24. The coding convention are very similar in Java and .NET. Hungarian was C++
25. I dont think Java is higher paying than .NET. At least in Indian companies programmer at the same grade get paid the same regardless of whther they are working on Java or .NET
26. No opinion..dont know much about P2P implementation
27. Check SQL2K5/Oracle102.g/DB/2 for integration with .NET
28. I would need a separate section for comments on throw clause in Java and you can read Anders Hejlsberg comment on that.
29. What do you mean by better structured diagramming???
30. Heard of SharpDevelope?
31. Java has a built in parse generator? check CodeDom
32.
33.
34. Open source .NET compiler from mono
35.
36. COM+, IIS integration
37. In my andmy customers experience, the developement lifecycles is slower on Java (primarily due to IDE support)
38. ADO.NET provides for wide variety of persistence, doesnt have to be DB only.. how about DataSet.WriteXml() ?
39. .NET is ECMA/ISO standard and yes SUN is a committee member on it.
40. What has hardware booster gotto do with either Java or .NET?
41. No licensing required for .NET. You only pay for VisualStudio. Dont want to? User SharpDeveloper
42. Heard of .NET CompactFramework and MicroFramework? Tiny CLR?
43. Care to produce benchmark for FastVM? In fact the initial MS VM for Java was faster than SUN's own VM
44. Check point 42.
45. JDK has Continuous build? or are you talking about IDE. VS compiles code in background from day 1.
46. Where did you discover a linker for .NET ;)
47. .NET supports ODBC and OLEDB drivers. Let me know which one you couldnt find
48. Code Analysis? Heard of VSTS?
49. MSN based on Java based tool? I would really like to know more of this. Link please?
50. ServerCLR vs. WorkstationCLR. Preoptimized based on application type, GC included
51. Reliability concers? elaborate?
52. Better Webservice interoperability? need some facts here
I dont think i have patience to respond to claims without facts and benchmarks and whole lot of inaccuracies...
