The java.DoubleAdder.doubleValue() is an inbuilt method in java that is equivalent to the method sum(), that is it returns current sum value. When the object of the class is created its initial value is zero.

Syntax:

public double doubleValue()

Parameters: The method does not accepts any parameter.

Return value: This method returns the current sum.

Below programs illustrate the above method:

Program 1:




// Program to demonstrate the doubleValue() method
  
import java.lang.*;
import java.util.concurrent.atomic.DoubleAdder;
  
public class GFG {
    public static void main(String args[])
    {
        DoubleAdder num = new DoubleAdder();
  
        // add operation on num
        num.add(42);
        num.add(10);
  
        // doubleValue operation on variable num
        num.doubleValue();
  
        // Print after doubleValue operation
        System.out.println("the value after doubleValue() is: " + num);
    }
}

Output:

the value after doubleValue() is: 52.0

Program 2:




// Program to demonstrate the doubleValue() method
  
import java.lang.*;
import java.util.concurrent.atomic.DoubleAdder;
  
public class GFG {
    public static void main(String args[])
    {
        DoubleAdder num = new DoubleAdder();
  
        // add operation on num
        num.add(72);
  
        // doubleValue operation on variable num
        num.doubleValue();
  
        // Print after doubleValue operation
        System.out.println("the value after doubleValue() is: " + num);
    }
}

Output:

the value after doubleValue() is: 72.0
