Redo-undo features at many places like editors, photoshop. Peek operations involve returning the topmost data element of the stack without removing it from the stack. Developed by JavaTpoint. To handle we need to check: 1. the current capacity of the Stack before pushing an element. After Performing the pop operations on the stack we get a string in reverse order. Deletion of an element from the top of the stack is called pop operation. What will be the capacity or initial capacity of the Stack? The basic operations that can be performed on a stack include push, pop, and peek, and stacks are commonly used in computer science for a variety of applications, including the evaluation of expressions, function calls, and memory management.There are two ways to implement a stack , Prepare for Microsoft & other Product Based Companies, Stack implementation in different language, Some questions related to Stack implementation, Introduction to Divide and Conquer Algorithm - Data Structure and Algorithm Tutorials, Introduction to Queue - Data Structure and Algorithm Tutorials, Introduction to Arrays - Data Structure and Algorithm Tutorials, Introduction to Linked List - Data Structure and Algorithm Tutorials, Introduction to Hashing - Data Structure and Algorithm Tutorials, Introduction to Tree - Data Structure and Algorithm Tutorials, Introduction to Backtracking - Data Structure and Algorithm Tutorials, Introduction to Graphs - Data Structure and Algorithm Tutorials, Introduction to Strings - Data Structure and Algorithm Tutorials, Introduction to Binary Tree - Data Structure and Algorithm Tutorials.

Learn to code interactively with step-by-step guidance. // 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 Removing a data element from the stack data structure is called a pop operation. Java provides a built Stack class that can be used to implement a stack. This is referred to as adding a new element at the top of the stack. Underflow conditions may occur if you try to return the topmost element if the stack is already empty. Stack is indeed a class and represent stack objects. Let's trying to pop out an empty stack is called underflow (throw an Exception). Requires extra memory due to the involvement of pointers. Stack also helps in implementing function call in computers.
