• Create a class “QueueEx”,
  • Define the method “print()” that accepts “Queue”,
    • Execute loop till queue size,
      • Assign the integer removed from the “Queue”.
      • Print the element.
      • Insert back the same element into the queue.
    • Print the queue of integers at the end.
  • Define the method “main()”,
    • Create object for “LinkedList”.
    • Call the “add()” method of queue to add the elements “3”, “4”, “5” and “6” into the “Queue” one by one.
    • Print the queue of integers at the start.
    • Call the method “print()” with “Queue” as a parameter.
