        input="java\\software\\";
        System.out.println("Before formating, input:" + input);
        try{           
            input=input.replaceAll("\\", "/");
            System.out.println("After formating, Input:" + input);
        }catch(Exception e){
            System.out.println("Error in formatting:" + e.getMessage());
        return input;
    }And I am getting this Error:
Unexpected internal error near index 1
Any idea whats wrong with above code?

If you want to replace two backslashes with asingle
forward slash, then you need to specify the former
(as a regular expression) as "\\\\"OH! Thanks. I got another way and its working.
I am using
s.replace('\\', '/'); insteadd of
replaceAll
Yes, that's definitely better in this case, since that API is simpler for single-char replacements. If you sometime need to replace strings though (back to the replaceAll) you'll need to be aware of how regular expressions are formed and how the backslash character plays a part in forming them.
