Spell.java:

   import java.io.*;
   import java.lang.*;
   //import scanner
   import java.util.Scanner;

   class Spell
   {
       public static void main(String[] args)
       {
           //create scanner
           Scanner input_str = new Scanner(System.in);
           //prompt the user
           System.out.println("\nEnter word to be tested.Enter quit to end....");
           //Reads first word as Input from the User.
           String input_word = input_str.nextLine();
           //Converts the words into LowerCase
           input_word = input_word.toLowerCase();
           //executes only if the word is not "quit".
           while(!input_word.equals("quit"))
           {
               //set the boolean varaiable as true initially for the given input.
               boolean hasProperty =    true;
               //using for loop, loop through all characcters
               for(int i=1;i<input_word.length();i++)
               {
                   char front_char = input_word.charAt(i);
                   char back_char = input_word.charAt(input_word.length()-i);
                   //checking if the reversed word and the origial word is equal or not
                   if(front_char != back_char)
                       hasProperty = false;
               }
               //if the property doesn't exist
               if(!hasProperty)
                   System.out.println("\n" + input_word + " does not have the property.");
               //if the property exist
               else
                   System.out.println("\n" + input_word + " have the property.");
               //read the next Input.
               input_word = input_str.nextLine();
           }
       }
