The java.util.concurrent.atomic.AtomicInteger.longValue() is an inbuilt method in java that returns the value which is currently stored in the object by converting it into a long data-type which is a primitive conversion.

Syntax:

public int longValue()

Parameters: The function does not accepts a single parameter.

Return value: The function returns the current value in Long data-type.

Program below demonstrates the function:

Program 1:




// Java program that demonstrates
// the longValue() 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);
  
        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.AtomicInteger;
  
public class GFG {
    public static void main(String args[])
    {
  
        // Initially value as 18
        AtomicInteger val
            = new AtomicInteger(18);
  
        long res = val.longValue();
  
        // Prints the updated value
        System.out.println("Current value: "
                           + res);
    }
}

Output:

Current value: 18
