AtomicLong longValue() method in Java with examples

Last Updated : 29 Jan, 2019
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 
// 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 
// 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
