\ or / for path

Question

Have difference? I know the back-slash need escape:
"\\folder\\subfolder\\file.txt"
"/folder/subfooder/file.txt"
There any difference? Exist some code that run one and not another? Because I use both, both works aleays and I never know why exist both.

Answer 1

As far as I know, java will replace delimiters according to operating system program runs on. So, if you will create path "/home/file.txt", if program runs on Windows, path will look like "\home\file.txt"
The only thing you need to consider is that, for example, path
"/folder/subfolder/file.txt" is considered absolute in Linux(/ is root folder) and relative in Windows (because it does not start with drive letter.)
