bufferedWriter.write写入时候,忽略换行符,如何解决?

String line;
line = bufferedReader.readLine();
while (line!=null){
line=bufferedReader.readLine();
finalData += line;
finalData += "\n";
// System.out.println("循环内" +finalData);
count++;
}

            bufferedReader.close();

// System.out.println("---------------");
// System.out.println("循环外"+finalData);
// System.out.println(count);
OutputStreamWriter writer = new OutputStreamWriter(fos,"gbk");
BufferedWriter bufferedWriter = new BufferedWriter(writer);
bufferedWriter.write(finalData);
bufferedWriter.newLine();
bufferedWriter.flush();
bufferedWriter.close();
