System.LoadLibrary can be used to load the libraries. Check this previous thread for example usage

Answer 3

您需要的只是Java本机接口http://docs.oracle.com/javase/1.5.0/docs/guide/jni/index.html

Answer 4

看到JNI，它旨在Java与其他语言进行交互...已经发布了许多链接

You need to use JNI to call native functions. In your case it you need to load Library first in memory using Runtime.getRuntime().loadLibrary( PATH_OF_DLL_FILE )
