Program not determining if the string is a palindrome

Question

having a slight issue with my program for class. the program should determine if the string the user inputs is a palindrome or not, the program itself can determine if a simple string like, "aba" is a palindrome but when the user inputs something such as, "one, two, three, two, one" it automatically declares it as not a palindrome. This program is in java, just wondering what i could change to allow the program to be able to read strings such as the second one.

import java.util.*;

class Palindrome
{
   public static void main(String args[])
  {
       String original, reverse="";
       Scanner in = new Scanner(System.in);

  System.out.println("Enter a string to check if it is a palindrome");
  original = in.nextLine();

  int length = original.length();

  for ( int i = length - 1 ; i >= 0 ; i-- )
     reverse = reverse + original.charAt(i);

  if (original.equals(reverse))
     System.out.println("Yo! That is a palindrome.");
  else
     System.out.println("No! That is not a palindrome.");

    }
  }

This is the code i'm working with at the moment.

您尝试过的字符串不是回文。.回文就像夫人一样，当您反转所有字母时，单词保持不变
