Queue Example in Java

Queue is a collection to store the data and follows the FIFO (First In First Out) pattern to remove the elements from it. Following is the implementation of Queue in java.

import java.util.LinkedList;
import java.util.Queue;

public class QueueDemo {
      public static void main(String[] args) {
            Queue<String> queue = new LinkedList<String>();
            for(int i=0; i<10; i++){
            System.out.print("\nElements present in Queue (First In First Out): ");
            for(String str: queue){
                  System.out.print(str + " ");
            System.out.print("\nRemoving Elements from Queue (First In First Out):");
                  System.out.print(queue.poll() + " ");
