        // create an atomic reference object
        // which stores Integer.
        AtomicReference<Integer> ref
            = new AtomicReference<Integer>();
  
        // set some value
        ref.set(12);
  
        // get and print value
        int value = ref.get();
        System.out.println("value  = " + value);
