Why does .split(“\\”) generate an exception?

Question

I have a String representing a directory, where \\ is used to separate folders. I want to split based on \"\\\\\":

String address = \"C         


        

Answer 1

String#split() method takes a regex. In regex, you need to escape the backslashes. And then for string literals in Java, you need to escape the backslash. In all, you need to use 4 backslashes:

String[] splited = address.split("\\\\");
