使用JSONParser类解析JSONString，找到下面的示例代码。

 JSONParser parser = new JSONParser();

        try {

            Object obj = parser.parse(new FileReader(
                    "/Users/Jiten/Documents/file1.txt"));

            JSONObject jsonObject = (JSONObject) obj;

            String name = (String) jsonObject.get("name");
            String author = (String) jsonObject.get("author");
            JSONArray companyList = (JSONArray) jsonObject.get("companyList");

            System.out.println("Name: " + name);
            System.out.println("Author: " + author);
            System.out.println("\nCompany List:");
            Iterator<String> iterator = companyList.iterator();
            while (iterator.hasNext()) {
                System.out.println(iterator.next());
            }

        } catch (Exception e) {
            e.printStackTrace();
        }
