实际上，下面的例子是StackOverFlow中的一个答案。我尝试使用下面的代码，但是，

JSONArray a = (JSONArray) parser.parse(new FileReader("c:\\exer4-courses.json"));

由于下面的异常，上面的行不起作用。

java.lang.ClassCastException: org.json.simple.JSONObject cannot be cast to org.json.simple.JSONArray

有没有办法读取我的JSON文件？
JSON文件：

[
    {
        "name": "John",
        "city": "Berlin",
        "cars": [
            "audi",
            "bmw"
        ],
        "job": "Teacher"
    },
    {
        "name": "Mark",
        "city": "Oslo",
        "cars": [
            "VW",
            "Toyata"
        ],
        "job": "Doctor"
    }
]

Java代码：

JSONArray a = (JSONArray) parser.parse(new FileReader("c:\\exer4-courses.json"));

for (Object o : a) {
    JSONObject person = (JSONObject) o;

    String name = (String) person.get("name");
    System.out.println(name);

    String city = (String) person.get("city");
    System.out.println(city);

    String job = (String) person.get("job");
    System.out.println(job);

    JSONArray cars = (JSONArray) jsonObject.get("cars");

    for (Object c : cars) {
      System.out.println(c + "");
    }
  }
