        // set some value
        ref.set(0, 234);
        ref.set(1, 134);
        ref.set(2, 325);
  
        // print the toString() return
        String toString = ref.toString();
        System.out.println(
            "String representation of"
            + " AtomicReferenceArray:\n"
            + toString);
    }
}
