以前的做分隔符獲取一個個字符串很是麻煩,其實JDK中的String 類已經很好的解決了這個問題。正則表達式確實是個好東西!
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" } |
