how to get name value associated with integer in dto

Question

i'm using java, for example, i have 2 tables staff(id, name, status_id, company_id) and company(id, name), the corresponding entity looks like:

public class Staff {
    private Integer id;
    private String name;
    private Integer statusId;
    private Integer companyId;
    private Company company;
}


public class Company {
    private Integer id;
    private String name;
    private List<Staff> staffList;
}

for status_id of table staff, 0 means New, 1 represents Active and 2 stands for Inactive.

I need to show New, Active or Inactive on html page/excel when describe a staff status rather than 0, 1 or 2.

And I have a StaffDto:

public class StaffDto {
    private Integer id;
    private String name;
    private Integer statusId;
    private String companyName;
}

my questions are:

1. the statusName(New/Active/Inactive) should be in StaffDto, such that there is no need to calculate status name according to statusId on each client, right?
2. what is a good practice to get statusName base on statusId? I should write code like

public class StaffDto {

    private Integer statusId;
    private String  statusName;

    public String getStatusName() {
        switch(statusId) {
        case 0: return "New";
        case 1: return "Active";
        case 2: return "Inactive";
        }
    }
}

is this a good practice? or something else(e.g. enum) is better?

3. if the logic of getting status name is added in StaffDto, what if there is another dtoj(e.g. ADto) also need to show status name, then I have to re-write this logic in ADto?

4. what if one client need to show New, Active or Inactive, while another client need to show A, B or C or something else, then what should I return in StaffDto? do I still return New, Active or Inactive in StaffDto, and other client need to calculate N, A or I base on statusId on their client? or should I return something else to client instead of xxxDto?

Answer 1

I too would go for enum as you mentioned, bind the status code to the name then, you do not have to rewrite the logic in DTOs, Make your model have the enum rather than code or name

enum can have its own methods like getShortName for different representations

enum Status {
    NEW(0), Active(1), InActive(2);
    private final int code;

    Status(int code) {
        this.code = code;
    }

    public String getShortName() {
        return this.name().substring(0, 1).toUpperCase();
    }

    public int getCode() {
        return code;
    }
}
