I don't know if this might sound silly, but is it possible to interact with hardware(say an audio card in my case) using Java.

Yes, it is possible. However, without a lot more information it's impossible to suggest much more than that. If you have a specific question then please update your post above with the details.

Yeah, I am sorry, but I have been asked to develop it in Java. I have used C++ before for sound operations using mmioAPIs but this project that I am going to work on contains several modules and one of the module is signal(generated by a digital hardware component) recording and replaying through different channels of a DAC card. Can this be done in Java? Anyway, the GUI of the application software should be written Java. This is must and should. I am new to Java and I use Eclipse IDE.
And I didn't down-vote you. Countered.

Thanks, but don't worry about it, a few downvotes never hurt anyone.
As to your main question I have not looked at the links that the other guys have offered but they may answer your query. I have worked on similar projects in the past and found the best solution was to write the low-level stuff in C/C++ and use the Java Native Interface[^] to access it from the Java application.

Thank you, I will look into it and get back.

Sound is a bit of a problem, most of the support has been turned down.
But yes, check this: [Java Sound API[^] @ oracle.com

In worst case you can implement your interaction in C/C++ modules for each supported platform and you can bind your native code to java via native method calls but thats a lot of work especially if you have a lot of different platforms to support. But you can reach any platform specific functionality from java if you are willing to write some platform specific C/C++ for it. In your case I would go with the sound api the guys already linked if its enough to get the job done.

Native methods in Java? I have to learn about them.

You can declare a static or instance method in java and by applying the native keyword on it you indicate for the compiler that you will provide the implementation with native code, and not in java. Then you have to write a DLL (or more DLLs) that exports the native function(s) with the appropriate names. When you java program starts you have to load the needed DLLs with System.LoadLibrary() before you call the native methods. Example: http://www.javaworld.com/javatips/jw-javatip23.html[^]
I would note that you should always try to write as much code in crossplatform java as you can and don't use native methods if you can avoid them because platform dependent stuff defeats the purpose of java.
