About Java processing strings

If there is a paragraph in English, such as: I am a student. My name is AAA. I like to swim, play basketball and play football. There are commas, little numbers, or other symbols (but if you encounter single quotes, such as my father ' s In the Father ' s to be alone as a word, how can you separate each word separately.

I wrote you a small example. ~ ~ 
//key is the use of regular expressions public 

class Stringtestone {public

 static void Main (string[] args) {
  String tags = "[, \\.\\s;!?] + ";//the Mark to be divided includes commas, periods, whitespace, exclamation marks, question mark ... You can add complete
  String line = "I am a student." My name is AAA. I like? Yes I am sure!  " +
    "to swim, play basketball and play football." My father ' s football! ';
  String [] re = line.split (tags);//split sentence according to given split tag ~ ~ for
  (int i = 0; i < re.length i + +) {
   System.out.println (i + 1) + ":" + re[i]);
}} Out put:
