java - 将Gson数组转换为Arraylist

我已经看到了很多这样的问题，但是我仍然无法解决这个问题。

我从服务器收到了一个json，其中包含多个gson数组。

我如何反序列化来自服务器的响应以满足这些模型。

主题模型：

public class Subject {
    public int SubjectId;
    public String SubjectName;
    public ArrayList Courses;
}

课程模式：

public class Course {
    public String CourseName;
    public String CourseDescription;
    public int CourseId;
    public int Subject_SubjectId;
}

编辑
这是服务器返回的内容：我使用了Google Chrome扩展程序PostMan来检索它。

这是实际的

最佳答案

您的json根本无法验证。

标签必须在" "中，所有=必须在:中

使用http://www.jslint.com/检查其他错误。

您尝试对其进行的任何json解析自然都会失败。
