        DoubleAccumulator num
            = new DoubleAccumulator(
                Double::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(42);
        num.accumulate(10);
  
        // before toString the value is
        System.out.println("DoubleAccumulator: "
                           + num.get());
  
        // Print String representation
        System.out.println("String representation: "
                           + num.toString());
    }
}
