JSONObject中的错误

Question

我在JSONObject中遇到编译错误：

构造函数JSONObject（String）未定义

    BufferedReader br = new BufferedReader(new FileReader("json.json"));
    StringBuilder sb = new StringBuilder();
    String line = br.readLine();
    while (line != null) {
        sb.append(line);
        line = br.readLine();
    }

    JSONObject jsonObj = new JSONObject(sb.toString());

尽管代码仅根据JSON文档

Answer 1

    BufferedReader br;
    try {
        br = new BufferedReader(new FileReader("json.json"));
        StringBuilder sb = new StringBuilder();
        String line = br.readLine();
        while (line != null) {
            sb.append(line);
            line = br.readLine();
        }
        JSONObject jsonObj = new JSONObject(sb.toString());
        System.out.println(jsonObj);
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

如果找不到文件，则应处理该异常。 我认为这对您有用。
