I think the answer is A) br.close(). It closes the input stream, allowing for the file to be overwritten.

But doesn't br.flush() flush the input stream? I'm not sure now.

I disagree, I believe the answer is D) bw.flush(). It flushes the output stream writer.

Haha, 'bw.flush();' is the way to go. It's like asking a plumber to install a sink without turning on the water, you know?

I bet the answer is 'bw.flush();'. You can't just leave all that data in the buffer, you gotta push it out there!

Gotta be 'bw.flush();', right? Otherwise, how's the computer gonna know to update the file? It's not a mind reader, you know!

Yeah, 'bw.flush();' makes sense to ensure the data is written to the file.

I think you're right, 'bw.flush();' is needed to update the file.

Hmm, 'bw.flush();' seems like the obvious choice here. I mean, who writes to a file without flushing the buffer? Amateurs, that's who!

I think line 'n1' should be 'bw.flush();' to ensure that all buffered output bytes are written out to the underlying output stream.

Yes, that makes sense. 'bw.flush();' would overwrite alldata.txt with data.txt.
