Question

我正在试图找到一种方法来将编码从读取文件更改为URL。这是代码的开始，但我尝试的所有内容都以语法错误结束。有什么建议？

public static void main(String[] args){
    readJson("jsonfilejson.txt");
}

public static void readJson(String file) { 

    Airline airLine = null;
    ArrayList<Airline> list = new ArrayList<Airline>();
    try {
            BufferedReader br = new BufferedReader(new FileReader(file));
            String line = "";
            String data = "";
            while((line=br.readLine())!=null){
                data += line;
            }
            ArrayList<String> flightsList = new ArrayList<String>();
            JSONObject jsonObject = new JSONObject(data);
            JSONArray jsonArray = jsonObject.getJSONArray("results");
            for (int i = 0; i < jsonArray.length(); i++) {
                JSONObject values = jsonArray.getJSONObject(i);
                JSONObject nameObject = values.getJSONObject("firstAirline");
                String name = nameObject.get("name").toString();
                JSONArray segmentArray = values.getJSONArray("segments");
                for (int j = 0; j < segmentArray.length(); j++) {
                    JSONObject segments = segmentArray.getJSONObject(j);
                    flightsList.add(segments.getString("flightNumber"));
                }
                String stops = values.get("stops").toString();
                JSONObject priceObject = values.getJSONObject("price");
                double price = Double.parseDouble(priceObject.get("amount").toString());

                airLine = new Airline(name, price, flightsList, Integer.parseInt(stops));
                list.add(airLine);
                flightsList.clear();
            }
    }

你似乎走在了正确的轨道上。尝试将您的字符串转换为您可以从中读取流的网址

 URL fileUrl = new URL(file);


    BufferedReader br = new BufferedReader(new InputStreamReader(fileUrl.openStream()));
