stack implementation using array in java geeksforgeeks

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. Push operation involves following two steps. // Stack implementation in Java class Stack { // store elements of stack private int arr []; // represent top of stack private int top; // total capacity of the stack private int capacity; // Creating a stack Stack (int size) { // initialize the array // initialize the stack variables arr = new int[size]; capacity = size; top = -1; } // push String reversal is also another application of stack. This is referred to as adding a new element at the top of the stack. Let's see how each operation can be implemented on the stack using array data structure.
