java寫文件UTF-8格式

String fileName = dir + File.separator + date + File.separator + (file.list().length + 1) + ".txt"; File file = new File(fileName); BufferedWriter writer = null; FileOutputStream writerStream = new FileOutputStream(file); writer = new BufferedWriter(new OutputStreamWriter(writerStream, "UTF-8")); StringBuilder strBuild = new StringBuilder(); writer.write(strBuild.toString());

注意上面的代碼最好放在catch中，而後在finally中添加

writer.flush(); writer.close();
