以前的做分隔符獲取一個(gè)個(gè)字符串很是麻煩，其實(shí)JDK中的String 類已經(jīng)很好的解決了這個(gè)問題。正則表達(dá)式確實(shí)是個(gè)好東西！
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" } |
