native

Example

Load a method from a compiled native library.

class Main {
  static {

  }

    public static void main(String[] args) {
    test();
  }

    private static native void test();
}

Definition and Usage

The native keyword declares a method as being part of an external compiled library that is specific to the operating system.

To use native methods, an external library must be loaded from a .dll, .so, or similar file. The compiled code in the external file must be written to support the Java Native Interface (JNI).
