A stack implementation using arrays is good, but most of the time people also use LinkedList to implement it, so that you do not have to resize once you exceed INITIAL_CAPACITY. Consider the simple example of plates stacked over one another in a canteen. Simply running through some test operations in the main () method is also barely . Stack is indeed a class and represent stack objects. Each program that is running in a computer system has its own memory allocations. Now, you will see how to do a stack implementation using an array: Adding an element on the top of the stack is termed a push operation. Your task is to use the class as shown in the comments in the code editor and complete the functions push() and pop() to implement a stack.  Example 1: Input: push(2) pu and Get Certified.

The pop operation returns the deleted element that was stored in another variable as a result. Insertion and deletion in an array are quite difficult as it stores the elements in consecutive memory locations. We are aware that the stack is a linear data structure based on the Last-in-first-out strategy (LIFO). How to implement stack using priority queue or heap?

As mentioned in @rolfl's to your later question, there is limited value in this class as elements cannot be easily retrieved. Stack is a linear Data Structure that is based on the LIFO concept (last in first out). But push is only an action on a stack, and thus should be a direct method of the Stack class, along with show and pop. I want the program to provide me to enter another option once the .

Stack is a linear data structure that follows the LIFO (Last In First Out) principle, where it performs all operations. The pop operation has two following steps: Stack data structure states an underflow condition when you try to delete a data element when the stack is already empty. Well, there will be a chance that the above APIs can throw an exception like: Error for Push Try to push an element into the Stack and Stack is already full.
