loadLibrary()


The java.lang.Runtime.loadLibrary(String filename) method loads the dynamic library with the specified library name. A file containing native code is loaded from the local file system from a place where library files are conventionally obtained. The details of this process are implementation-dependent. The mapping from a library name to a specific filename is done in a system-specific manner. First, if there is a security manager, its checkLink method is called with the libname as its argument. This may result in a security exception. The method System.loadLibrary(String) is the conventional and convenient means of invoking this method. If native methods are to be used in the implementation of a class, a standard strategy is to put the native code in a library file (call it LibFile) and then to put a static initializer:

Syntax:
static { System.loadLibrary("LibFile"); }


Example:

public class RuntimeDemo {

   public static void main(String[] args) {

      // print when the program starts
      System.out.println("Program starting...");

      // load a library that is Windows/System32 folder
      System.out.println("Loading Library...");
      Runtime.getRuntime().loadLibrary("C:/Windows/System32/crypt32.dll");
      System.out.println("Library Loaded.");

   }
}
