DoubleAccumulator get() method in Java with Examples

The Java.DoubleAccumulator.get() method is an inbuilt method in Java that returns the current value in this DoubleAccumulator instance. It means it only returns the current value and does not takes any parameter. The return type is int.

Syntax:

public double get()

Parameters: The function does not accepts any parameter.

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

Below programs illustrate the above method:

Program 1:

// Java program to demonstrate
// the get() 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(2);
        num.accumulate(10);

        // Gets current value
        double x = num.get();

        // Print after get operation
        System.out.println("Current value is: "
                           + x);
    }
}

Output:

Current value is: 12.0

Program 2:

// Java program to demonstrate
// the get() 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(24);
        num.accumulate(1);

        // Gets current value
        double x = num.get();

        // Print after get operation
        System.out.println("Current value is: "
                           + x);
    }
}

Output:

Current value is: 25.0
