We would like to know how to test a String for Palindrome.
A palindrome is a word, a verse, a sentence, or a number that reads the same in forward and backward directions.
The following code shows how to check if a string is palindrome.
public class Main { public static void main(String[] args) { String str2 = "noon"; System.out.println(isPalindrome(str2)); }//from w ww . j a v a 2s . com public static boolean isPalindrome(String inputString) { int len = inputString.length(); if (len <= 1) { return true; } String newStr = inputString.toUpperCase(); boolean result = true; int counter = len / 2; for (int i = 0; i < counter; i++) { if (newStr.charAt(i) != newStr.charAt(len - 1 - i)) { result = false; break; } } return result; } }
The code above generates the following result.
