import java.util.Scanner;

public class NameValidation{
    public static void main(String []args){
        Scanner amante = new Scanner(System.in);
       
        String str = "";
       
            do{
            System.out.println("Enter a word: ");
            str= amante.nextLine();
           
            char FirstCharacter = str.charAt(0);
            char LastCharacter = str.charAt(str.length()-1);
           
            if(str.equals("exit"))      
                System.out.println("Program is now terminating…");
            else if(FirstCharacter == LastCharacter)
               
                System.out.println("The first character is equal to its last character.");
            else
                System.out.println("The first character is not equal to its last character.");
            }
            while(!(str.equalsIgnoreCase("exit")));
