# How can I rename a file in Java?

How can I [rename](https://www.mindstick.com/interview/23303/how-to-rename-extention-of-mdf-file) a [file](https://www.mindstick.com/articles/59/encrypting-and-decrypting-files-using-c-sharp) from Java.io?

```
File temporaryFile = File.createTempFile();
temporaryFile.renameTo(newfileName);
```

And if newfileName is [exists](https://www.mindstick.com/forum/158947/how-do-you-use-the-exists-operator-to-check-for-the-existence-of-records-in-a-subquery) then its fails.

How do I do a force rename?
