各位先進前輩們，想請益請教，接收到後端所傳遞的資料時遇到的問題:
Array層層包，包的小弟眼花撩亂
小弟利用Bean 把資料類型先分出如下

public class Bean{

    private List<RetObj> retObj;
        public List<RetObj> getRetObj() {
        return retObj;
    }

    public void setRetObj(List<RetObj> retObj) {
        this.retObj = retObj;
    }
    
        public static class RetObj {
        private String id;
        @SerializedName("1")
        private String list1;
        @SerializedName("2")
        private String list2;
        @SerializedName("3")
        private String list3;
        @SerializedName("4")
        private String list4;
        private List<detail[]> detail;

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getList1() {
            return list1;
        }

        public void setList1(String list1) {
            this.list1 = list1;
        }

        public String getList2() {
            return list2;
        }

        public void setList2(String list2) {
            this.list2 = list2;
        }

        public String getList3() {
            return list3;
        }

        public void setList3(String list3) {
            this.list3 = list3;
        }

        public String getList4() {
            return list4;
        }

        public void setList4(String list4) {
            this.list4 = list4;
        }

        public List<MedicineDataBean.detail[]> getDetail() {
            return detail;
        }

        public void setDetail(List<MedicineDataBean.detail[]> detail) {
            this.detail = detail;
        }
    }
        public static class detail {
        @SerializedName("1")
        private String detailList1;
        @SerializedName("2")
        private String detailList2;
        @SerializedName("3")
        private String detailList3;
        @SerializedName("4")
        private String detailList4;

        public String getDetailList1() {
            return detailList1;
        }

        public void setDetailList1(String detailList1) {
            this.detailList1 = detailList1;
        }

        public String getDetailList2() {
            return detailList2;
        }

        public void setDetailList2(String detailList2) {
            this.detailList2 = detailList2;
        }

        public String getDetailList3() {
            return detailList3;
        }

        public void setDetailList3(String detailList3) {
            this.detailList3 = detailList3;
        }

        public String getDetailList4() {
            return detailList4;
        }

        public void setDetailList4(String detailList4) {
            this.detailList4 = detailList4;
        }
    }
}

在解析資料方面的語法，如下

  Gson gson = new Gson();
  Type listType = new TypeToken<Collection<Bean>>() {}.getType();
  Bean bean = gson.fromJson(result, listType);

請各位前輩，指點指點，小弟哪裡有錯誤，或是可以往哪個方向去尋找答案。
感恩感謝<(_ _)>
