flush() writes the content of the buffer to the destination and makes the buffer empty for further data to store but it does not closes the stream permanently. That means you can still write some more data to the stream.
But close() closes the stream permanently. If you want to write some data further, then you have to reopen the stream again and append the data with the existing ones.
