I'm not sure, but I think both A) and D) are necessary to ensure that the data is written correctly to alldata.txt.

I disagree, I believe the answer is A) br.close() because we need to close the BufferedReader before writing to the file.

I think the answer is D) bw.flush() because it will flush the contents of the BufferedWriter to the file.

I think B) bw.writeln() is also a valid option, as writing a line to the BufferedWriter could also overwrite the file.

Nieves, the question is about overwriting the file, so flushing the BufferedWriter makes more sense.

I'm not sure, but I think A) br.close() would be needed to close the BufferedReader.

I agree with Lai, because flushing the BufferedWriter will write the data to the file.
