// Java program to print queue elements

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

public class Main {
  public static void main(String[] args) {
    Queue < Integer > queue = new LinkedList < > ();

    queue.add(10);
    queue.add(20);
    queue.add(30);
    queue.add(40);

    for (int item: queue) {
      System.out.print(item + " ");
    }

  }
}

Output:

Queue elements: 
10 20 30 40 50

Explanation:

In the above program, we imported the "java.util.LinkedList" and "java.util.Queue" packages to use the Queue Interface and LinkedList collection respectively. Here, we created a class Main. The Main class contains a main() method. The main() method is the entry point for the program.

In the main() method, we created a queue using the LinkedList collection and added items to it. Then we accessed queue elements using the foreach loop and printed the result.
