Unlike ArrayList, there is no get(int index) method in Queue to retrieve the element at specified position.
Anybody please tell me how to achieve this in Queue?
Thanks.

The element() method of Queue Interface returns the element at the front the container. It does not deletes the element in the container. This method returns the head of the queue. This method differs from peek() only in that it throws an exception if this queue is empty.
To remove elements from a Java Queue , you call the remove() method. This method removes the element at the head of the Queue .
To remove an element from a Queue, use the remove() method.
Removing an item from a queue in Python: To remove items from a queue in Python, we will be using the “get function”. See the Python Queue example given below. To make sure that our queue is empty, we can use the empty function which will return Boolean values.
Accessing elements by index is not part of the concept of a queue.
If you need to access elements by index, you want a list, not a queue.
