以前的做分隔符获取一个个字符串很是麻烦，其实JDK中的String 类已经很好的解决了这个问题。正则表达式确实是个好东西！
split
public String[] split(String regex)
- Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
The string "boo:and:foo", for example, yields the following results with these expressions:
| Regex |
Result |
| : |
{ "boo", "and", "foo" } |
| o |
{ "b", "", ":and:f" } |
