Java URL separator or File.separator
提问by Ondrej Tokar
I have checked similar qestions where they suggested to use Stringas a parameter. But that is what I do.
我已经检查过类似的问题，他们建议将其String用作参数。但这就是我所做的。
My Code:
我的代码：
uri.lastIndexOf(File.separator)
Where uriis: file:/C:/Users/[email protected]/workspace/Maersk_Line_GaTracking/bin/
在哪里uri：file:/C:/Users/[email protected]/workspace/Maersk_Line_GaTracking/bin/
Maybe that is because Windows uses back slashes as file separator. But why then, when I retrieve the URI, I am getting forward slashes?
也许这是因为 Windows 使用反斜杠作为文件分隔符。但是为什么那么，当我检索 URI 时，我得到了正斜杠？
String uri = DataRetrieval.class.getProtectionDomain().getCodeSource().getLocation() + "";

There's a difference between file names and URIs. File names use \as a separator on Windows, but URIs alwaysuse /.
文件名和 URI 之间存在差异。文件名\在 Windows 上用作分隔符，但 URI始终使用/.
So if you're splitting file names, search for File.Separator, and if you're splitting URIs, search for '/'
因此，如果要拆分文件名，请搜索 File.Separator，如果要拆分 URI，请搜索 '/'
OH, I should mention: /alsoworks as a separator in most windows APIs, so for filenames, it's usually a good idea to map all the forward slashes to File.Separator before you start messing with it.
哦，我应该提到： 在大多数 Windows API 中/也可用作分隔符，因此对于文件名，通常最好在开始使用 File.Separator 之前将所有正斜杠映射到 File.Separator。

URIs are defined to use /as their component separator.
URI 被定义为/用作它们的组件分隔符。
