DoubleAccumulator doubleValue() method in Java with Examples
  • Last Updated : 29 Jan, 2019

The Java.DoubleAccumulator.doubleValue() is an inbuilt method in java that is equivalent to get() method, it means it only returns the current value and does not takes any parameter. The return type of this method is int.

Syntax:

public double doubleValue()

Parameters: The function does not accepts any parameter.

Return value: The method returns the current value of the DoubleAccumulator instance.

Program below demonstrates the function:



Program 1:




// Java program to demonstrate the
// doubleValue() method
  
import java.lang.*;
import java.util.concurrent.atomic.DoubleAccumulator;
  
public class GFG {
    public static void main(String args[])
    {
  
        DoubleAccumulator num
            = new DoubleAccumulator(
                Double::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(42);
        num.accumulate(10);
  
        // Print before doubleValue operation
        System.out.println("Old value is: "
                           + num);
  
        // Print after doubleValue operation
        System.out.println("Current double value is: "
                           + num.doubleValue());
    }
}
Output:
Old value is: 52.0
Current double value is: 52.0

Program 2:




// Java program to demonstrate the
// doubleValue() method
  
import java.lang.*;
import java.util.concurrent.atomic.DoubleAccumulator;
  
public class GFG {
    public static void main(String args[])
    {
  
        DoubleAccumulator num
            = new DoubleAccumulator(
                Double::sum, 0L);
  
        // accumulate operation on num
        num.accumulate(32);
        num.accumulate(45);
  
        // Print before doubleValue operation
        System.out.println("Old value is: "
                           + num);
  
        // Print after doubleValue operation
        System.out.println("Current double value is: "
                           + num.doubleValue());
    }
}
Output:
Old value is: 77.0
Current double value is: 77.0
