The Java.util.concurrent.atomic.AtomicLongArray.length() is an inbuilt method in Java that returns the length of the AtomicLongArray. This method does not accepts any parameter and returns the length of the AtomicLongArray which is of type int.
Syntax:
public final int length()
Parameters: The function does not accept any parameter.
Return Value: The function returns the length of the AtomicLongArray.
Below programs illustrate the above method:
Program 1:
// Java program that demonstrates// the length() function  import java.util.concurrent.atomic.AtomicLongArray;  public class GFG {    public static void main(String args[])    {        // Initializing an array        long a[] = { 11, 12, 13, 14, 15 };          // Initializing an AtomicLongArray with array a        AtomicLongArray arr = new AtomicLongArray(a);          // Displaying the length of the AtomicLongArray        System.out.println("The length of the array : "                           + arr.length());    }} |
Output:
The length of the array : 5
Program 2:
// Java program that demonstrates// the length() function  import java.util.concurrent.atomic.AtomicLongArray;  public class GFG {    public static void main(String args[])    {        // Initializing an array        long a[] = { 11, 12, 13, 14, 15, 16, 17 };          // Initializing an AtomicLongArray with array a        AtomicLongArray arr = new AtomicLongArray(a);          // Displaying the length of the AtomicLongArray        System.out.println("The length of the array : "                           + arr.length());    }} |
Output:
The length of the array : 7
