Java is platform independend and therefore you cannot do platform specific things. By definition java code should be able to run on any platform, and linux queues are not going to work on windows or mac.
But if you have a command prompt command that you can use, you can use Runtime.exec() to call it and get the output. Perhaps you can do something with that. Or perhaps if you do a google search you can find a third party API that can work with these queues. If all else fails, you can use JNI to call a native library that you write yourself. Since you know C, you should be able to figure that out.
