java如何向重复的枚举类型添加多个值
我在大学里有两个enum班。java和学生。爪哇
下面是这两个类的代码片段
public enum College {
ID("Id of College"), NAME("Name of College"), ADDRESS("Address of College");
private final String description;
private College(String details) {
this.description = description;
}
}
public enum Student {
ROLL(College.ID, "Roll No of Student"), CLASS(College.NAME, "Class of Student"),
PLACE(College.ADDRESS, "Place of Student"), STUDENTID(setMap());
private final String description;
private final College college;
private Map<college, String> attributes;
private Student(College college, String details) {
this.college = college;
this.details = details;
}
private Student(Map<college, String> attributes) {
this.attributes = attributes;
for(college key: attributes.keySet()) {
this.college=key;
this.description=attributes.get(key);
}
}
private Map<college, String> setMap() {
Map<college, String> map = new HashMap<college, String>();
map.put(College.ID ,"ID of college");
map.put(College.NAME,"Name of Student");
map.put(College.ADDRESS,"Address of the College");
return map;
}
}
我的问题是,我无法在要标记多个学院枚举的学生类中添加STUDENTID枚举。 例如:
STUDENTID((College.ID ,"ID of college"),(College.NAME,"Name of Student"),(College.ADDRESS,"Address of the College"));
这只是一个示例,但我想将多个学院类枚举标记为学生类。有办法吗?请帮帮我

正如@Sweeper所建议的,您需要一个合适的构造函数,请尝试下面的方法
