Question

我想解析一个文件并使用2＆＃39;新行＆＃39; （\ n）作为稀释而不是EOL并将其添加到字符串对象中。

这是算法 -

1. While end of file is not reached
2. Read a file until you hit 2 \n's or eof is reached
  put that contents as a string to a List object. 
3. go to 1.

Answer 1

您可以使用Scanner.useDelimiter()方法。

public Scanner useDelimiter(String pattern)

将此扫描仪的分隔模式设置为由其构造的模式指定的字符串。

According to JLS新行

LineTerminator：

the ASCII LF character, also known as "newline"

the ASCII CR character, also known as "return"

the ASCII CR character followed by the ASCII LF character

Answer 2

您可以使用任何所需的分隔符。如果你use Scanner you can set the delimiter。

注意：新行通常为(\r\n|\r|\n)，以支持新行的三种变体。

在您的情况下，最简单的解决方案可能是

String[] paragraphs = FileUtils.readFileAsString(filename)
                               .split("(\r\n|\r|\n){2}");

读取文件时，我可以使用EOF或EOL以外的其他稀释剂
