What is the best Java program to implement stack?
That makes sense. And what about the linked list implementation?
With a linked list implementation, you create a node class that contains both the element to be stored and a reference to the next node in the list. You keep track of the head of the linked list, which is the first node in the list or the one containing the top element. When you push an element onto the stack, you create a new node, set its element to the value being added, and set its next reference to the current head of the list. You then set the head to the new node. When you pop an element off the stack, you retrieve the element from the head node, set the head to its next node, and return the element.
