        Reader reader = jSONParser.getGSONFromUrl(url);
    Root response=null;
    try {
        response = new Gson().fromJson(reader, Root.class);
        person
        = new ArrayList<Person>(Arrays.asList(response.person.clone()));
       children 
       = new ArrayList<Child>(Arrays.asList(response.Children.clone()));
       job
        = response.job;
        } catch (Exception e) {
        // TODO: handle exception
        System.out.println("JSONReader "+e.getMessage());

public class Root{  
    @SerializedName("person")       
    Person[] persons;
    @SerializedName("job")
    Job job;

Answer 1

要获取名称，您需要具有以下路径：

children.name

如果你有一个名字数组，你应该作为一个数组访问：

children.name.firstname[number]

由于您的“名称”是一个对象类型，您可以通过“。”引用它的任何字段。
