java - 连接字符串中的绝对文件路径

Question

我需要在一个字符串中连接几个绝对文件路径。但如果我使用字符，它可能是文件名或路径的一部分，字符串将会困惑。可以使用哪种分隔符？

现在我使用 File.pathSeparator，对于 Windows 7，它是“;”。但这个字符可以是文件名的一部分。

Answer 1

您可以使用File.pathSeparator :

The system-dependent path-separator character, represented as a string for convenience. This string contains a single character, namely pathSeparatorChar:

The system-dependent path-separator character. This field is initialized to contain the first character of the value of the system property path.separator. This character is used to separate filenames in a sequence of files given as a path list. On UNIX systems, this character is ':'; on Microsoft Windows systems it is ';'.
