The Java.util.concurrent.atomic.AtomicLong.longValue() is an inbuilt method in java that returns the value which is currently stored in the object and its data-type is long.
Syntax:
public long longValue()
Parameters: The function does not accepts a single parameter.
Return value: The function returns the current value in Long data-type.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates// the longValue() 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);          long res            = val.longValue();          // Prints the updated value        System.out.println("Current value: "                           + res);    }} |
Output:
Current value: 0
Program 2:
// Java program that demonstrates// the longValue() 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);          long res = val.longValue();          // Prints the updated value        System.out.println("Current value: "                           + res);    }} |
Output:
Current value: 18
