This method is used to create a shallow copy of the Queue. It just creates a copy of the Queue. The copy will have a reference to a clone of the internal elements but not a reference to the original elements.
Syntax: public virtual object Clone ();
Return Value: The method returns an Object which is just the shallow copy of the Queue.
Example 1: Let’s see an example without using a Clone() method and directly copying a Queue using assignment operator ‘=’. In the below code, we can see even if we Dequeue() elements from myQueue2, contents of myQueue is also changed. This is because ‘=’ just assigns the reference of myQueue to myQueue2 and does not create any new Queue. But Clone() creates a new Queue.
