![]() ![]() Adding Elements to the Stack In order to add elements to the stack, the push () method is invoked. Syntax to Create a Stack Stack identifier new Stack () type is the kind of object we are going to create, and identifier is the reference variable.We have discussed an algorithm to letâs write a java code to implement this algorithm. The stack program in Java shows the usage of the stack in the program. Java Program to Reverse a String using Stack After that when we pop the character first a is popped out followed by v, a, j. When we push the characters in a stack first j is pushed followed by a, v, a. To understand this letâs take an example. Once all the characters are pushed the next step is to pop the characters from a stack. Here are the algorithm âįirst we have to push all the characters of a string in a stack. We can use the property of stack data structure to reverse a string. ![]() In Stack, Insertion and Deletion operations are known as push and pop. In LIFO, an element which inserted at last is the first element to be deleted. It is also called LIFO (Last In First Out) data structure. StackĪ stack is linear data structure in which insertion and deletion operations are allowed only at one end. In my previous tutorial, I have explained java program to reverse a string using recursion.Ä«efore solving this problem, Letâs understand what is a stack data structure. Given an input string, We have to write a java code to reverse a string using stack. ![]() Write a java program to reverse a string using stack data structure. ![]()
