/*
 * public String substring(int beginIndex, int
 *                                        endIndex)
 *
 * Parameters:
 * ---------- 
 * beginIndex - the beginning index, inclusive.
 * endIndex - the ending index, exclusive.
 *
 * Returns:
 * -------
 * Returns a string that is a substring of this
 * string. The substring begins at the specified
 * beginIndex and extends to the character at index
 * endIndex - 1. Thus the length of the substring is
 * endIndex-beginIndex.
