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); } } |
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); } } |
Current value: 18
