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

here, checking for the largest palindrome in a string, always starting from 1st char.

public static String largestPalindromeInString(String in) {
    int right = in.length() - 1;
    int left = 0;
    char[] word = in.toCharArray();
    while (right > left && word[right] != word[left]) {
        right--;
    }
    int lenght = right + 1;
    while (right > left && word[right] == word[left]) {

        left++;
        right--;

    }
    if (0 >= right - left) {
        return new String(Arrays.copyOf(word, lenght ));
    } else {
        return largestPalindromeInString(
                new String(Arrays.copyOf(word, in.length() - 1)));
    }
}
