java 利用Scanner解析逗号字符串

对形如"a,b,c,d,e"类字符串的解析，所用的正则表达式：[\\s*,*\\s]

Scanner sc = new Scanner(System.in);
Pattern p = Pattern.compile("[\\s*,*\\s]"); 
sc.useDelimiter(p);

或者

Scanner sc = new Scanner(System.in);
sc.useDelimiter("[\\s*,*\\s]"); 

A Scanner breaks its input into tokens using a  delimiter pattern, which by default matches whitespace. The resulting  tokens may then be converted into values of different types using the  various next methods。
