解決BufferedReade 中文乱码

读取txt文件乱码：

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

 

解决办法：

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

BufferedReader read = new BufferedReader(isr);

 

因为InputStreamReader和BufferedReader都继承自Reader,而BufferedReader的构造器又是Reader.
