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
// Java Program Demonstrate remove()// method of ConcurrentLinkedQueueimport java.util.concurrent.*;public class GFG { public static void main(String[] args) { // create an ConcurrentLinkedQueue ConcurrentLinkedQueue<Integer> queue = new ConcurrentLinkedQueue<Integer>(); // Add Numbers to queue queue.add(4353); queue.add(7824); queue.add(78249); queue.add(8724); // Displaying the existing ConcurrentLinkedQueue System.out.println("ConcurrentLinkedQueue: " + queue); // apply remove() for Number 78249 boolean response = queue.remove(78249); // print results System.out.println("Removing Number 78249 successful: " + response); // Displaying the existing ConcurrentLinkedQueue 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
// Java Program Demonstrate remove()// method of ConcurrentLinkedQueueimport java.util.concurrent.*;public class GFG { public static void main(String[] args) { // create an ConcurrentLinkedQueue ConcurrentLinkedQueue<String> queue = new ConcurrentLinkedQueue<String>(); // Add String to queue queue.add("Aman"); queue.add("Amar"); queue.add("Sanjeet"); queue.add("Rabi"); // Displaying the existing ConcurrentLinkedQueue System.out.println("ConcurrentLinkedQueue: " + queue); // apply remove() on queue boolean response1 = queue.remove("Aman"); // print after applying remove method System.out.println("Removing String \"Aman\" successful: " + response1); // Displaying the existing ConcurrentLinkedQueue System.out.println("Updated ConcurrentLinkedQueue: " + queue); // apply remove() on queue boolean response2 = queue.remove("Kisan"); // print after applying remove method System.out.println("Removing String \"Kisan\" successful: " + response2); // Displaying the existing ConcurrentLinkedQueue 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]
