palindrome series in java

import java.util.*; class PalindromeExample2 { public static void main(String args[]) { String original, reverse = ""; // Objects of String class Scanner in = new Scanner(System.in); System.out.println("Enter a string/number to check if it is a palindrome"); original = in.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/number is a palindrome."); else System.out.println("Entered string/number isn't a palindrome."); } }

package test //The function below checks if a string is a palindrome //True = Is a palindrome & False = Not a palindrome public boolean isPalindromString(String text){ String reverse = reverse(text); if(text.equals(reverse)) { return true; } return false; } //This function returns the reverse String of its input. //Ex. if given "hello", it will return "olleh" public String reverse(String input) { if(input == null || input.isEmpty()) { return input; } return input.charAt(input.length()- 1) + reverse(input.substring(0, input.length() - 1)); }
