escaping backslash in java string literal
提问by Eypros
I am using Java for a while and come up with this problem: I use hard-coded paths in windows like
我使用 Java 有一段时间了，并提出了这个问题：我在 Windows 中使用硬编码路径，例如
"D:\Java-code\JavaProjects\workspace\eypros\src"
The problem is that I need to escape the backslash character in order to use it with string. So I manually escape each backslash:
问题是我需要转义反斜杠字符才能将其与字符串一起使用。所以我手动转义每个反斜杠：
"D:\Java-code\JavaProjects\workspace\eypros\src"
Is there a way to automatically take the unescaped path and return an escaped java string.
有没有办法自动采用未转义的路径并返回转义的java字符串。
I am thinking that maybe another container besides java string could do the trick (but I don't know any).
我想也许除了 java string 之外的另一个容器可以解决这个问题（但我不知道）。
Any suggestions?
有什么建议？

public static String escapePath(String path)
{
return path.replace("\", "\\");
}
The \is doubled since it must be escaped in those strings also.
将\增加一倍，因为它必须在这些字符串进行转义也。
Anyway, I think you should use System.getProperty("file.separator");instead of \.
无论如何，我认为你应该使用System.getProperty("file.separator");而不是\.
Also the java.io.Filehas a few methods useful for file-system paths.
还有java.io.File一些对文件系统路径有用的方法。
