// Program to demonstrate the longValue() method
  
import java.lang.*;
import java.util.concurrent.atomic.LongAccumulator;
  
public class GFG {
    public static void main(String args[])
    {
        LongAccumulator num = new LongAccumulator(Long::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(42);
        num.accumulate(10);
  
        // longValues current value
        num.longValue();
  
        // Print after longValue operation
        System.out.println(" the current value is: " + num);
    }
}
