我已經在很多方面進行拆分他們都沒有工作

下面是我已經使用的幾個。

split("\n--\n"); 
split("^\\s"); 
split("\\n--\\n")

他們都沒有工作

''''另請參閱https://stackoverflow.com/questions/454908/split-java-string-by-new-line –

@ScaryWombat試圖它不起作用 – user2727493

檢查新行字符正在使用 –

使用這個表達式：(?m)^--$\R?

(?m)允許多模式
^匹配行
--比賽的開始字符--
$匹配行的末尾
\R?任選地匹配斷行

即匹配一條只包含兩條破折號（-）字符的行，包括行結尾的換行符（如果存在）。

從Java代碼，即：

String[] paragraphs = input.split("(?m)^--$\\R?");

舉證見IDEONE。
