3  The Java String class compareTo() method compares the given 
4  string with the current string lexicographically. 
5  It returns a positive number, negative number, or 0.
6  ___________________________________________
7  	if s1 > s2, it returns positive number  
8	if s1 < s2, it returns negative number  
9	if s1 == s2, it returns 0
