    {
  
        // Initialized with 0
        LongAdder num = new LongAdder();
  
        // Print the initial value
        System.out.println("Initial value is: "
                           + num);
  
        // Add 6 to it
        num.add(6);
  
        // Print the final value
        System.out.println("After addition"
                           + " of 6, value is: "
                           + num);
  
        // Add 5 to it
        num.add(5);
  
        // Print the final value
        System.out.println("After addition"
                           + " of 5, value is: "
                           + num);
  
        // reset operation on num
        num.reset();
  
        // Print after value
        System.out.println("After reset: "
                           + num);
    }
}
