Syntax:

public static boolean isNative(int mod)

Parameters: This method accepts a integer names as mod represents a set of modifiers.



Return: This method returns true if mod includes the native modifier, false otherwise.

        // check Modifier is native or not
        boolean result = Modifier.isNative(mod);
  
        System.out.println("Mod integer value "
                           + mod + " is native : "
                           + result);
    }
  
    class Calculator {
        native void addNumbers();
    }
}
