The length() method of a AtomicReferenceArray class is used to return the length of this AtomicReferenceArray.
Syntax:
public final int length()
Parameters: This method accepts nothing.
Return value: This method returns the integer representing length of this AtomicReferenceArray.
Below programs illustrate the length() method:
Program 1:
// Java program to demonstrate// AtomicReferenceArray.length() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create an atomic reference object. AtomicReferenceArray<Integer> ref = new AtomicReferenceArray<Integer>(5); // print the length int length = ref.length(); System.out.println( "length of AtomicReferenceArray = " + length); }} |
Output:
length of AtomicReferenceArray = 5
Program 2:
// Java program to demonstrate// AtomicReferenceArray.length() method import java.util.concurrent.atomic.*; public class GFG { public static void main(String[] args) { // create a array of Strings String[] names = { "AMAN", "AMAR", "SURAJ" }; // create an atomic reference object. AtomicReferenceArray<String> ref = new AtomicReferenceArray<String>(names); // print the length int length = ref.length(); System.out.println( "length of AtomicReferenceArray = " + length); }} |
Output:
length of AtomicReferenceArray = 3
