Difference between System.getProperty("line.separator"); and "\n" ?
提问by Tilak Maddy
While developing GUI with Java FX , I seem to get different results with System.getProperty("line.separator"); and "\n" during writing to a file or getting data from internet. What basically is the difference ?

System.getProperty("line.separator")
returns the OS dependent line separator.
System.getProperty("line.separator")
返回依赖于操作系统的行分隔符。
On Windows it returns "\r\n"
, on Unix "\n"
. So if you want to generate a file with line endings for the current operating systems use System.getProperty("line.separator")
or write using a PrintWriter
.
在 Windows 上它返回"\r\n"
,在 Unix 上"\n"
。因此,如果要为当前操作系统生成带有行结尾的文件,请使用System.getProperty("line.separator")
或使用PrintWriter
.

on the Windows platform, System.getProperty("line.separator") is "\r\n", "\n" (Linux and MacOS X), "\r" (MacOS 9 and older)
在 Windows 平台上, System.getProperty("line.separator") 是 "\r\n"、"\n"(Linux 和 MacOS X)、"\r"(MacOS 9 及更早版本)

System.getProperty("line.separator")
is platform dependent:
System.getProperty("line.separator")
是平台相关的:
- "\n" on UNIX style machines
- "\r\n" on Windows machines
- "\n" 在 UNIX 风格的机器上
- "\r\n" 在 Windows 机器上
Whereas "\n" is only "\n".
而“\n”只是“\n”。

?\n? is the line separator for most operating systems such as Linux/Unix. To ensure the compatibility with any operating system, query this value with System.getproperty
?\n? 是大多数操作系统(如 Linux/Unix)的行分隔符。为确保与任何操作系统兼容,请使用 System.getproperty 查询此值
