How do I delete a row in a csv file?

Question

I am currently working on an application and I have now read in the csv file and am able to paste it out to the user.

I am now however attempting to delete a single row of the csv file or a "log" as the file is supposed to be a data log.

I have been looking around and everywhere is saying something different I am new to java and this is confusing. I hope the following code is helpful.

        scFile.useDelimiter(""); //sets the delimiter pattern
        while (scFile.hasNext()) //returns a boolean value
        {
        System.out.print(scFile.next()); //find and returns the next complete token from this scanner
        }
