Hint: use the substring method. Here is the documentation:
public String substring (int beginIndex, int endIndex) Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Parameters: beginIndex - the beginning index, inclusive. endIndex - the ending index, exclusive. Returns: the specified substring.
Try to figure out what they mean by ``inclusive'' and ``exclusive.'' Run a couple of experiments to see if you are right.
Write a recursive method named isPalindrome that takes a String and that returns a boolean indicating whether the word is a palindrome or not.
