ConcurrentLinkedQueue in Java
The ConcurrentLinkedQueue class in Java is used to implement a queue using a concurrent linked list. This class implements the Collection interface as well as the AbstractCollection class. It is a part of the Java Collection Framework.
A program that demonstrates this is given as follows −
Example
import java.util.concurrent.*;
public class Demo {
public static void main(String[] args) {
ConcurrentLinkedQueue<String> clQueue = new ConcurrentLinkedQueue<String>();
clQueue.add("Amy");
clQueue.add("John");
clQueue.add("May");
clQueue.add("Harry");
clQueue.add("Anne");
System.out.println("The elements in ConcurrentLinkedQueue are: " + clQueue);
}
}The output of the above program is as follows −
Output
The elements in ConcurrentLinkedQueue are: [Amy, John, May, Harry, Anne]
Now let us understand the above program.
The ConcurrentLinkedQueue is created and then elements are added to it. Finally, it is displayed. A code snippet that demonstrates this is given as follows −
ConcurrentLinkedQueue<String> clQueue = new ConcurrentLinkedQueue<String>();
clQueue.add("Amy");
clQueue.add("John");
clQueue.add("May");
clQueue.add("Harry");
clQueue.add("Anne");
System.out.println("The elements in ConcurrentLinkedQueue are: " + clQueue);
