Explanation

A: copies only, don't move operation B,C,D (no try-with-resource !) syntax change to: try { ... B: throws FileAlreadyExistsException C: correct if syntax change to : StandardCopyOption.REPLACE_EXISTING (before REPLACE_Existing) D: throws FileAlreadyExistsException E: works properly if the sourcefile has the correct format, utf-8 here (else throws MalformedInputException) AND syntax is corrected to: try ( BufferedReader br = Files.newBufferedReader(Paths.get(source), Charset.forName("UTF- BufferedWriter bw = Files.newBufferedWriter(Paths.get(dest), Charset.forName("UTF-8)); ){ String record = "";
