Not A Statement Error in Recursive method

I wrote this simple recursive method to check if a number is palindrome. 

public boolean isPalindrome(int x) {
        String str = Integer.toString(x);
        if(str.length() <= 1){
            return true;
        }
        else{
            char first = str.charAt(0);
            char last = str.charAt(str.length()-1);

            if (first == last){
                int short = Integer.parseInt(str.substring(1, str.length()-1));
                return isPalindrome(short);
            }
            else{
                return false;
            }
        }
  }

However, I keep getting the compile error that this line int short = Integer.parseInt(str.substring(1, str.length()-1)); is not a statement. Can anyone see what the problem is? Thanks!

Rename the variable name- short, it is a java keyword.

if (first == last){
                return isPalindrome(Integer.parseInt(str.substring(1, str.length()-1)));
            }
