用java进行文件转码方法

BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream("C:/**/**.csv"), "UTF-8"));
            StringBuilder sb = new StringBuilder();
            String line = "";
            while ((line = br.readLine()) != null) {
                sb.append(new String(line.getBytes("GKB"),"GKB") + "\n");
            }

 使用

sb.toString().getBytes("GBK")
