java - 读取文件时可以使用 EOF 或 EOL 以外的其他分隔符吗

Question

我想解析一个文件并使用 2 个“换行符”(\n) 作为分隔符而不是 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)

Sets this scanner's delimiting pattern to a pattern constructed from the specified String.

According to JLS新行是

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
