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");

    }
