Remove an element from a Queue in Java



To remove an element from a Queue, use the remove() method.

First, set a Queue and insert some elements −

Queue<String> q = new LinkedList<String>(); q.offer("abc"); q.offer("def"); q.offer("ghi"); q.offer("jkl"); q.offer("mno"); q.offer("pqr"); q.offer("stu"); q.offer("vwx");

Remove the first element −

System.out.println("Queue head = " + q.element()); System.out.println("Removing element from queue = " + q.remove());

The following is an example −

Example

 Live Demo

import java.util.LinkedList; import java.util.Queue; public class Demo {    public static void main(String[] args) {       Queue<String> q = new LinkedList<String>();       q.offer("abc");       q.offer("def");       q.offer("ghi");       q.offer("jkl");       q.offer("mno");       q.offer("pqr");       q.offer("stu");       q.offer("vwx");       System.out.println("Queue head = " + q.element());       System.out.println("Removing element from queue = " + q.remove());       System.out.println("\nRemaining Queue elements...");       Object ob;       while ((ob = q.poll()) != null) {          System.out.println(ob);       }    } }

Output

Queue head = abc Removing element from queue = abc Queue head now = abc Remaining Queue elements... def ghi jkl mno pqr stu vwx
