    /**

     * Compares two strings lexicographically. 

     * The comparison is based on the Unicode value of each character in

     * the strings. The character sequence represented by this 

     * String object is compared lexicographically to the 

     * character sequence represented by the argument string. The result is 

     * a negative integer if this String object 

     * lexicographically precedes the argument string. The result is a 

     * positive integer if this String object lexicographically 

     * follows the argument string. The result is zero if the strings

     * are equal; compareTo returns 0 exactly when 

     * the {@link #equals(Object)} method would return true. 

     * 


     * This is the definition of lexicographic ordering. If two strings are 

     * different, then either they have different characters at some index 

     * that is a valid index for both strings, or their lengths are different, 

     * or both. If they have different characters at one or more index 

     * positions, let k be the smallest such index; then the string

     * whose character at position k has the smaller value, as 

     * determined by using the < operator, lexicographically precedes the 

     * other string. In this case, compareTo returns the 

     * difference of the two character values at position k in 

     * the two string -- that is, the value:

     * 


     * this.charAt(k)-anotherString.charAt(k)

     * 


     * If there is no index position at which they differ, then the shorter 

     * string lexicographically precedes the longer string. In this case, 

     * compareTo returns the difference of the lengths of the 

     * strings -- that is, the value: 

     * 


     * this.length()-anotherString.length()

     * 


     *

     * @param   anotherString   the String to be compared.

     * @return  the value 0 if the argument string is equal to

     *          this string; a value less than 0 if this string

     *          is lexicographically less than the string argument; and a

     *          value greater than 0 if this string is

     *          lexicographically greater than the string argument.

     * @exception java.lang.NullPointerException if anotherString 

     *          is null.
