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
