我有一个文件在我的sd卡扩展名是abc.ser和文件包含JSON对象一样

{"music":"abc","highqualityavailable":"true","cacheable":"true"}
{"music":"xyz","highqualityavailable":"false","cacheable":"true"}
{"music":"aaa","highqualityavailable":"true","cacheable":"true"}
{"music":"bbb","highqualityavailable":"false","cacheable":"true"}
{"music":"ccc","highqualityavailable":"true","cacheable":"true"}

该文件包含JSON对象，但不是JSON的正确格式，我如何在我的应用程序中读取或解析它，我已经读取了文件中的字符串，但不知道如何将其转换为POJO

String root = Environment.getExternalStorageDirectory().getAbsolutePath();

                File file = new File(root+"/tmp/playerSongsString.ser");

                if (file.exists()) {

                    FileInputStream stream = null;

                    try {

                        stream = new FileInputStream(file);
                        FileChannel fc = stream.getChannel();
                        MappedByteBuffer bb =    fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
                      /* Instead of using default, pass in a decoder. */
                        jString = Charset.defaultCharset().decode(bb).toString();

                        JSONObject object = new JSONObject(jString);

                        Log.d("json:",jString);



                    } catch (IOException e) {
                        e.printStackTrace();
                    } catch (JSONException e) {
                        e.printStackTrace();
                    } finally {
                        try {
                            stream.close();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
