If a function checks for palindromes recursively, what will isPalindrome("radar") return?

public static boolean isPalindrome(String s) {
    if (s.length() <= 1) return true;
    else if (s.charAt(0) == s.charAt(s.length() - 1))
        return isPalindrome(s.substring(1, s.length() - 1));
    else return false;
}
