Check string for palindrome

Question

A palindrome is a word, phrase, number or other sequence of units that can be read the same way in either direction.

To check whether a word is a palindrome I get th

Answer 1

Alternatively, recursion.

For anybody who is looking for a shorter recursive solution, to check if a given string satisfies as a palindrome:

private boolean isPalindrome(String s) {
    int length = s.length();

    if (length < 2) // If the string only has 1 char or is empty
        return true;
    else {
        // Check opposite ends of the string for equality
        if (s.charAt(0) != s.charAt(length - 1))
            return false;
        // Function call for string with the two ends snipped off
        else
            return isPalindrome(s.substring(1, length - 1));
    }
}

OR even shorter, if you'd like:

private boolean isPalindrome(String s) {
    int length = s.length();
    if (length < 2) return true;
    return s.charAt(0) != s.charAt(length - 1) ? false :
            isPalindrome(s.substring(1, length - 1));
}
