SOLUTION:

import java.lang.String;

import java.util.Scanner;

class q3

{

 public static void main(String args[])

 {

  String str;

  int i = 0,j;

  Scanner sc = new Scanner(System.in);

  System.out.print("Enter a Word: ");

  str = sc.nextLine();

  j = str.length() - 1;

  while(i < str.length() / 2)

  {

  if(str.charAt(i) != str.charAt(j))

  {

System.out.println("Not a Palindrome.");

  System.exit(0);

  }

  ++i;

--j;

  }

  System.out.println("A Palindrome.");
