I believe inorder to check palindrome we need to check the word is same from backward to forward. For this i reverse the word by every char and concat to new String and check for Equal value of both String objects.

import java.io.; import java.util.;

public class Solution {

public static void main(String[] args) {

    Scanner sc=new Scanner(System.in);
    String A=sc.next();
    /* Enter your code here. Print output to STDOUT. */
    String k ="";
    for(int i =A.length()-1;i>=0;i--){
        char c = A.charAt(i);
        String ch = Character.toString(c);
        k = k.concat(ch);
    }
    if(A.equals(k))
    {
        System.out.println("Yes");
    }
    else 
        System.out.println("No");

}

}
