How to use File.separator in Windows

Question

Every time I use File.separator in Java code, I get the error because '\\' is an escape character in Windows and Java doesn't recognise "quotes".

I tried doing this: String[] split = strData.toString().split(File.pathSeparator); , but it crashes with following error message:

Caused by: java.util.regex.PatternSyntaxException: Unexpected internal error near index 1
\
^

File.pathSeparator = ;
File.separator = \
strData.toString() = C:\Users\server\Desktop\minecraft\plugins\krneki

由于String.split的参数是一个正则表达式，您需要引用分隔符才能将其视为文字：

String[] split = strData.toString().split(Pattern.quote(File.pathSeparator));
