n the PalindromeStack class, write Java code for the followingquestion by adding code at the comment labeled ADD YOUR CODEHERE.
/* Write a Java program thatuses ArrayStack (array stack fromChapter 3)
* to determine whether an input stringis a palindrome.
* A palindrome is a string of characters(a word, phrase, or
* sentence) that is the same regardlessof whether you read it
* forward or backward.
*
* Here are two sample runs:
* Enter a string: abcdcba
* The input string is a palindrome.
*
* Enter a string: abcdefg
* The input string is not apalindrome.
