Question

Write a method called printPalindrome that accepts a Scanner for the console as a parameter, and prompts the user to enter one or more words and prints whether the entered String is a palindrome (i.e., reads the same forwards as it does backwards, like "abba" or "racecar"). If the following Scanner object were declared: Scanner console = new Scanner(System.in); printPalindrome(console); The resulting output for a call where the user types a palindrome would be: Type one or more words: racecar racecar is a palindrome! The output for a call where the user types a word that is not a palindrome would be: Type one or more words: hello hello is not a palindrome. For an added challenge, make the code case-insensitive, so that words like "Abba" and "Madam" will be considered palindromes.

Explanation / Answer

import java.util.*; class Palindrome { public static void main(String args[]) { String original, reverse=""; Scanner console = new Scanner(System.in); printPalindrome(console); System.out.println("Enter a string to check if it is a palindrome"); original = console.nextLine(); int length = original.length(); for ( int i = length - 1 ; i >= 0 ; i-- ) reverse = reverse + original.charAt(i); if (original.equals(reverse)) System.out.println("Entered string is a palindrome."); else System.out.println("Entered string is not a palindrome."); } }
