 Write a program that reads a string and determines whether it is a palindrome

import java.util.Scanner;

class StringPalindrome

{

 public static void main(String[] args) 

 {

       String str,rstr="";

       int len,i,sum=0;

       Scanner scr=new Scanner(System.in);

       System.out.println("Enter any string ");

       str=scr.next();

       len=str.length();

       for(i=0;i<len;i++)

       {

        char ch=str.charAt(i);

        rstr=ch+rstr;

       }

       if(str.compareTo(rstr)==0)

        System.out.println("Input String is palindrome");

       else

        System.out.println("Input String is not palindrome");

  }

}
