How to replace backward slash to forward slash using java?

Question

I'm importing a CSV file to MySQL database. This can be done using java.mysql support for forward slash in file path. If user gives the path

c:\upload\date\csv\sample.csv 

MySQL doesn't support this type of path pattern. I want to search for backslashes in the path and replace them with a forward slash, to give this:

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

How is that done?

Answer 1

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.

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('\\', '/');
