1. Suppose we have a new student whose name is "mcDonald Jones". Although we don't know exactly why the letter "m" is written in lowercase, when we arrange the order of English names, our rule should be case-insensitive. That is, both uppercase "M" and lowercase "m" should be in front of "S".
  2. Re-write the getName() method in the previous exercise so that it will handle the sorting rule. You don't have to modify anything in the main() function. Everything is handled by the object itself. This is the advantage of "encapsulation" in object-oriented programming.
  3. To make strings case-insensitive, you may simply convert all characters to uppercase by the method string.upper(), or to lowercase by the method string.lower().
  4. By the way, Chinese characters are ordered by the number of strokes. Therefore, if we have another student 文天祥, you may see that his position is before 柳宗元.
  5. The output may look like 
    Julia Roberts
mcDonald Jones
Sandra Bullock
文天祥
柳宗元
蘇東坡
