Bufferedwriter works, but file empty?

Question

I have the following code:

CSVmaker(LinkedList data) {
    String [] myLines = makeStrings(data);
  //  for (int k = 0; k

        

Answer 1

Though the question is answered . I would like to add how buffer works.

whenever you try to write to a file using buffer,whatever you write gets added to the buffer. When the buffer is full the contents are written to the file . This way we are reducing the number of hits to the hard-drive hence improving the efficency.

If we want to forcefully write to a file without the buffer getting full , we use flush() method.
