讀取txt文件亂碼

BufferedReader read = new BufferedReader(new FileReader(new File(filename)));  

解決辦法：

InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "UTF-8");  BufferedReader read = new BufferedReader(isr);  

因為InputStreamReader和BufferedReader 都繼承自Reader,而BufferedReader 的構(gòu)造器又是Reader.

Writer也是一樣的處理

FileOutputStream writerStream = new FileOutputStream(filePath, true);  BufferedWriter oWriter = new BufferedWriter(new OutputStreamWriter(writerStream, "UTF-8"));
