    static String string;
  
    public static void main(String[] args)
        throws NoSuchFieldException,
               SecurityException
    {
  
        // get Field class object
        Field field
            = GFG.class
                  .getDeclaredField("string");
  
        // get Modifier Integer value
        int mod = field.getModifiers();
  
        // check Modifier is static or not
        boolean result = Modifier.isStatic(mod);
  
        System.out.println("Mod integer value "
                           + mod + " is static : "
                           + result);
    }
