如何从bufferreader reader.readline() 获取特定编码的字符串

关键是在imputstreamreader 的设定的时候选定编码格式。就能获得该编码格式的字符串
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.

    public static void main(String[] args) throws Exception {        // TODO Auto-generated method stub        System.out.println("start");        Process p =null;        String command = "cmd /c copy c:\\test\\tt.jpg c:\\";        p=Runtime.getRuntime().exec(command);          BufferedReader reader = new BufferedReader(new InputStreamReader(p.getInputStream(),"gbk"));          String line;          while((line = reader.readLine())!= null){              System.out.println(line);          }        System.out.println("end");    }
