Question

Define a class to accept a string, convert it into lowercase and check whether the string is a palindrome or not.

A palindrome is a word that reads the same backward as forward.

Example:

madam, racecar etc.

Answer 1

public class Palindrome
{
     public static void main(String args[])
     {
         String a, b = "";
         Scanner s = new Scanner(System.in);
         System.out.print("Enter the string you want to check:");
         a = s.nextLine();
         a = a.toLowercase();
         int n = a.length();
         for{int i = n - 1; i >= 0; i--)
         {
              b = b + a.charAt(i);
         }
              if( a;equalsIgnoreCase(b)) 
        {
             System.out.println("The string is palindrome."); 
        }
            else
            {
                System. out.println("The string is not a palindrome."); 
             }
      }
}
