Java 枚举和抽象类添加状态值

public enum CourseTypeEnum {
    VIDEO_COURSE(1,"录制课程"),
    LIVE_COURSE(2,"直播课程"),
    OFFINE_COURSE(3,"线下课程");
    private int seq;
    private  String desc;

        this.seq=seq;
        this.desc=desc;
    }
    public int getSeq(){
        return seq;
    }
    public String gtDesc(){
        return desc;
    }
}

    public static  final int PASSED_COURSE=3;
    public static  final int NOT_PASSED_COURSE=4;
    public static final int DELETED_COURSE=5;
}

public class Test {
    public static void main(String[] args) {
        public void getPackgeCourse(Long packageId,Long userId){
