AtomicLong doubleValue() method in Java with examples Last Updated : 29 Jan, 2019 Summarize Comments Improve Suggest changes Share Like Article Like Report The Java.util.concurrent.atomic.AtomicLong.doubleValue() is an inbuilt method in java which returns the current value of the AtomicLong 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. Below programs illustrate the above method: Program 1: Java // Java program that demonstrates // the doubleValue() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 0 AtomicLong val = new AtomicLong(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 Program 2: Java // Java program that demonstrates // the doubleValue() function import java.util.concurrent.atomic.AtomicLong; public class GFG { public static void main(String args[]) { // Initially value as 18 AtomicLong val = new AtomicLong(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 Reference: https://docs.oracle.com/javase/8/docs/api/java/util/concurrent/atomic/AtomicLong.html#doubleValue-- Comment More infoAdvertise with us Next Article Byte doubleValue() method in Java with examples G gopaldave Follow Improve Article Tags : Java Java - util package Java-Functions Java-AtomicLong Practice Tags : Java Similar Reads 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.
