Practical 7: Write a program to find that given number or string is palindrome or not.

Program:

import java.util.*;

class practical7

{

   public static void main(String args[])

   {

      String original, reverse = "";

      Scanner in = new Scanner(System.in);

      System.out.println("Enter a string 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 is a palindrome.");

      else

         System.out.println("Entered string is not a palindrome.");

   }

}

Output:
