AtomicInteger doubleValue() method in Java with examples

The java.util.concurrent.atomic.AtomicInteger.doubleValue() is an inbuilt method in java which returns the current value of the AtomicInteger as a Double data-type after performing primitive conversion.

Syntax:

public double doubleValue()

Parameters: The function does not accepts any parameter.

Return value: The function returns the numeric value represented by this object after conversion to type double.

Program below demonstrates the function:

Program 1:

// Java Program to demonstrates
// the doubleValue() function

import java.util.concurrent.atomic.AtomicInteger;

public class GFG {
    public static void main(String args[])
    {

        // Initially value as 0
        AtomicInteger val
            = new AtomicInteger(0);

        val.addAndGet(7);

        // Prints the updated value
        System.out.println("Previous value: "
                           + val);

        // Gets the double value
        double res = val.doubleValue();

        System.out.println("Double value: "
                           + res);
    }
}

Output:

Previous value: 7
Double value: 7.0

// Java Program to demonstrates
// the doubleValue() function

import java.util.concurrent.atomic.AtomicInteger;

public class GFG {
    public static void main(String args[])
    {

        // Initially value as 18
        AtomicInteger val
            = new AtomicInteger(18);

        val.addAndGet(7);

        // Gets the double value
        System.out.println("Previous value: "
                           + val);

        // Decreases the value by 1
        double res = val.doubleValue();

        System.out.println("Double value: "
                           + res);
    }
}

Output:

Previous value: 25
Double value: 25.0
