Example of ConcurrentLinkedQueue in Java
November 15, 2023
ConcurrentLinkedQueue is based on linked node. It is named as ConcurrentLinkedQueue because it is thread safe and can be accessed concurrently. It is available from Java 5.
2. As a property of queue,
ConcurrentLinkedQueue follows FIFO. Element is added to the tail of the queue and element is pull out from head.
3.
ConcurrentLinkedQueue is used in multi-threaded environment.
Example
package com.concretepage;
import java.util.Iterator;
import java.util.concurrent.ConcurrentLinkedQueue;
public class ConcurrentLinkedQueueTest {
ConcurrentLinkedQueue<String> clq= new ConcurrentLinkedQueue<String>();
class AddThread implements Runnable{
@Override
public void run() {
//ads the element to the tail of element
clq.add("A");
//insert the elements to the tail of element
clq.offer("B");
// retrieve and removes the elements from head
clq.poll();
Iterator<String> itr= clq.iterator();
while(itr.hasNext()){
System.out.println(itr.next());
}
}
}
public static void main(String... args){
new Thread(new ConcurrentLinkedQueueTest().new AddThread()).start();
new Thread(new ConcurrentLinkedQueueTest().new AddThread()).start();
}
}
