Aug 9, 2017 · return false; } } } } If the string is made of no letters or just one letter, it is a palindrome. Otherwise, compare the first and last letters of the string. If the first and last letters differ, then the string is not a palindrome. Otherwise, the first and last letters are the same.
Mar 20, 2019 · 1. You could check if the array is palindrome by comparing it with reversed copy of the original array. Using ArrayUtils.reverse from Apache commons: int[] arrCopy = Arrays.copyOf(array, array.length); ArrayUtils.reverse(arrCopy); boolean isPalindrome = Arrays.equals(array, arrCopy);
Jun 28, 2015 · I am trying to create a Palindrome program using recursion within Java but I am stuck, this is what I have so far: public static void main (String[] args){ System.out.println(isPalindrome("noon"...
Jan 28, 2014 · 7. I need an algorithm that verify with the fastest possible execution time, if a string is a palindrome ( the string can be a proposition with uppercase or lowercase letter, spaces etc.). All of this in Java. I got a sample : bool isPalindrome(string s) {. int n = s.length(); s = s.toLowerCase(); for (int i = 0; i < (n / 2) + 1; ++i) {.
You can check if a string is a palindrome by comparing it to the reverse of itself: public static boolean isPalindrome(String str) { return str.equals(new StringBuilder(str).reverse().toString()); }

Here is what I have so far: String palindrome = "..."; boolean isPalindrome = palindrome.equals(. new StringBuilder(palindrome).reverse().toString()); My problem with this is that it does not consider a word like: Race car to be a palindrome.
