Need help with String Manipulation

[vagelisceid]

Hi I'm trying to build my own web file system and I want to find a solution about this problem. I want replace let's say for example this string: dir:\subdir\file.txt
with this one: dir:\\subdir\\file.txt. All I want to do is replace the sigle backslash with double backslash. I've searched all the web web and yet haven't found a way to do it. Could anyone help me?

Shouldn't String's method replace(CharSequence,CharSequence) work?

well my problem was not to find the appropriate methods but how to handle special characters backslash and double backslash. Anyway I've found how to do this. replaceAll("\\\\","\\\\\\\\")
