Answer 1

If you have:

String s = "c:\\upload\\date\\csv\\sample.csv";

In Java, you can just use:

s = s.replace("\\", "/");

Which will make s equal to:

c:/upload/date/csv/sample.csv

Answer 2

The String.replace(CharSequence, CharSequence) example provided by @PaulPRO and @Bohemian will work, but its better to use the String.replace(char, char) version. Slightly faster. Though you won't have a noticeable speed difference, its better to do such optimisations where possible.

String replacedStr = str.replace('\\', '/');

Answer 3

In java, use this:

str = str.replace("\\", "/");

Note that the regex version of replace, ie replaceAll(), is not required here; replace() still replaces all occurrences of the search term, but it searches for literal Strings, not regex matches.
