Is there an effective tool to convert C  code to Java code

User · Answer

Possibly you could use jni4net - opensource bridge instead   Or list of other options I know

User · Answer

They don t convert directly  but it allows for interoperability between  NET and J2EE   http   www mainsoft com products index aspx

User · Answer

C  has a few more features than Java   Take delegates for example  Many very simple C  applications use delegates  while the Java folks figures that the observer pattern was sufficient   So  in order for a tool to convert a C  application which uses delegates it would have to translate the structure from using delegates to an implementation of the observer pattern  Another problem is the fact that C  methods are not virtual by default while Java methods are   Additionally  Java doesn t have a way to make methods non virtual   This creates another problem  an application in C  could leverage non virtual method behavior through polymorphism in a way the does not translate directly to Java  If you look around you will probably find that there are lots of tools to convert Java to C  since it is a simpler language  please don t flame me I didn t say worse I said simpler   however  you will find very few if any decent tools that convert C  to Java   I would recommend changing your approach to converting from Java to C  as it will create fewer headaches in the long run   Db4Objects recently released their internal tool which they use to convert Db4o into C  to the public   It is called Sharpen   If you register with their site you can view this link with instructions on how to use Sharpen  http   developer db4o com Resources view aspx Reference Sharpen How To Setup Sharpen   I ve been registered with them for a while and they re good about not spamming

There is a tool from Microsoft to convert java to C   For the opposite direction take a look here and here  If this doesn t work out  it should not take too long to convert the source manually because C  and java are very similar

I m not sure what you are trying to do by wishing to convert C  to java  but if it is  net interoperability that you need  you might want to check out Mono

Why not write it in Haxe  http   haxe org   and convert it to whatever you want it to be

User · Answer

Although this is an old-ish question  take a look at xmlVM http   www xmlvm org clr2jvm  I m not sure if it s mature enough yet  although it has been around for several years now  XMLvm was made  I believe  primarily for translating Android Java apps to the iPhone  however  its XML-code-translation-based framework is flexible enough to do other combinations  see the diagrams on the site    As for a reason to do this conversion  maybe there is a need to  hijack  some of the highly abundant oss code out there and use it within his their own  Java  project   Cheers  Rich

Try to look at Net2Java It seems to me the best option for automatic  or semi-automatic at least  conversion from C  to Java

User · Answer

We have an application that we need to maintain in both C  and Java  Since we actively maintain this product  a one-time port wasn t an option  We investigated Net2Java and the Mainsoft tools  but neither met our requirements  Net2Java for lack of robustness and Mainsoft for cost and lack of source code conversion   We created our own tool called CS2J that runs as part of our nightly build script and does a very effective port of our C  code to Java  Right now it is precisely good enough to translate our application  but would have a long way to go before being considered a comprehensive tool  We ve licensed the technology to a few parties with similar needs and we re toying with the idea of releasing it publicly  but our core business just keeps us too busy these days

I have never encountered a C - Java conversion tool   The syntax would be easy enough  but the frameworks are dramatically different   Even if there were a tool  I would strongly advise against it   I have worked on several  migration  projects  and can t say emphatically enough that while conversion seems like a good choice  conversion projects always always always turn in to money pits   It s not a shortcut  what you end up with is code that is not readable  and doesn t take advantage of the target language   speaking from personal experience  assume that a rewrite is the cheaper option

Well the syntax is almost the same but they rely on different frameworks so the only way to convert is by getting someone who knows both languages and convert the code    the answer to your question is no there is no  effective  tool to convert c  to java
