The remove(Object o) method of ConcurrentLinkedQueue is used to remove a single instance of the specified element from this ConcurrentLinkedQueue, if it is present. This method removes an element e such that o.equals(e) if this ConcurrentLinkedQueue contains one or more such elements. Remove() method returns true if this ConcurrentLinkedQueue contained the specified element else it will return false. Syntax:
public boolean remove(Object o)
Parameter: This method takes a parameter o which represent element to be removed from this ConcurrentLinkedQueue. Returns: This method returns true if this ConcurrentLinkedQueue contained the specified element and removed. Below programs illustrate remove() method of ConcurrentLinkedQueue: Example 1:
Java
import java.util.concurrent.*;
public class GFG {
public static void main(String[] args)
{
ConcurrentLinkedQueue<Integer>
queue = new ConcurrentLinkedQueue<Integer>();
queue.add( 4353 );
queue.add( 7824 );
queue.add( 78249 );
queue.add( 8724 );
System.out.println("ConcurrentLinkedQueue: " + queue);
boolean response = queue.remove( 78249 );
System.out.println("Removing Number 78249 successful: " + response);
System.out.println("Updated ConcurrentLinkedQueue: " + queue);
}
}
|
Output:
ConcurrentLinkedQueue: [4353, 7824, 78249, 8724]
Removing Number 78249 successful: true
Updated ConcurrentLinkedQueue: [4353, 7824, 8724]
Example 2:
Java
import java.util.concurrent.*;
public class GFG {
public static void main(String[] args)
{
ConcurrentLinkedQueue<String>
queue = new ConcurrentLinkedQueue<String>();
queue.add("Aman");
queue.add("Amar");
queue.add("Sanjeet");
queue.add("Rabi");
System.out.println("ConcurrentLinkedQueue: " + queue);
boolean response1 = queue.remove("Aman");
System.out.println("Removing String \"Aman\" successful: " + response1);
System.out.println("Updated ConcurrentLinkedQueue: " + queue);
boolean response2 = queue.remove("Kisan");
System.out.println("Removing String \"Kisan\" successful: " + response2);
System.out.println("Updated ConcurrentLinkedQueue: " + queue);
}
}

Output:
ConcurrentLinkedQueue: [Aman, Amar, Sanjeet, Rabi]
Removing String "Aman" successful: true
Updated ConcurrentLinkedQueue: [Amar, Sanjeet, Rabi]
Removing String "Kisan" successful: false
Updated ConcurrentLinkedQueue: [Amar, Sanjeet, Rabi]
