For your practice, code each of these methods by accessing the internal variables of the ArrayBoundedStack class, not by calling the previously defined public methods of the class. 1. Implement a size () method in the ArrayBoundedStack class. The method-call returns the count of how many elements/items are on the stack. 2. Implement a printStack () method in the ArrayBoundedStack class. The method- call on a stack should print all its contents. You may assume that the order in which you print the contents doesn't matter. Test your method implementations with the help of a driver program.
