![]() ReverseString = reverseString + inputString.charAt(i) ("Enter a string to check if it is a palindrome:") įor ( int i = length - 1 i >= 0 i- ) Scanner scanner = new Scanner(System.in) In the last step, similar to the above programs, the string and reverseString are compared to check if the input string is palindrome. These characters read in reverse order are appended to the reverseString. Here, we are iterating over the string in reverse order (from length-1 to 0) and reading the corresponding character using charAt() method. You just need to have a basic understanding of for loop and if.else statement to understand this program. Program 3: Using for loop/While loop and String function charAt ("The input String is not a palindrome.") ReverseString = reverseString+queue.remove() In the last step compare the string and reverseString to check if the string is palindrome or not. The pop() method removes the last character from the stack. The program runs a while loop until the stack is empty and at each iteration removes the last character of the string using pop() method and adds it to the reverseString variable. Once all the characters of the given string are added to the stack. The program iterates over the input string by running a loop from 1 to the length of the string and adds each character of the string to the stack using push() method. There are following three ways to check for palindrome string.ģ) Using for/while loop Program 1: Palindrome check Using Stack ![]() #STRING LIST STACK QUEUE ARE EXAMPLES OF HOW TO#In this tutorial, you will learn how to write a java program check whether the given String is Palindrome or not. ![]()
