Below image shows the output of the above longest palindrome java program. We can improve the above code by moving the palindrome and longest lengths check into a different function. However, I have left that part for you. :) Please let me know if there are any other better implementations...

In this article, we’re going to see how we can check whether a givenStringis a palindrome using Java. A palindrome is a word, phrase, number, or other sequences of characters which reads the same backward as forward, such as “madam” or “racecar”. ...
A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward as forward, such as madam. Write a java program to find the longest palindrome present in a given string. For example, in the string a
