    Default Help needed with enum

    Hi there!

    First, I'm sorry if my post doesn't belong here, I registered today so I'm new here. I'm also french, so english is not my native language - sorry if I'm not precise and if you don't understand my message.

    I'm trying to create an enumeration called Origin with 3 parameters : a String (name), a list of Competence (which is a class that I created myself), and a list of Aspect (which I also created myself). I tried to create objects into this enumeration, but whatever I tried, I didn't manage to create one Origin. Here are some parts from my code, if you understood my explanation and have an element that might help me, thanks in advance!

    public enum Competence {
      Admin("Admin"),
      Medic("Medic"),
      Worker("Worker");
     
      private String name;
     
      Competence(String name) {
        this.name = name;
      }
    }
     
    public class Aspect {
      private String name;
     
      public Aspect(String name) {
        this.name = name;
      }
    }
     
    public enum Origin {
      Batra("Batra", "HERE IS THE Competence[]", "HERE IS THE Aspect[]");
     
      private String name;
      private Competence[] competences;
      private Aspect[] aspects;
     
      Origin(String name, Competence[] competences, Aspect[] aspects) {
        this.name = name;
        this.competences = competences;
        this.aspects = aspects;
      }
    }

    Once again, thank you in advance if you have an element that could help me progress in my personal project!

    There is an example for enum in the tutorial:
    https://docs.oracle.com/javase/tutor...vaOO/enum.html

    If you get error messages you need help with, copy the full text and paste it here.
    If you don't understand my answer, don't ignore it, ask a question.

    It seems like you're on the right track with your code. However, you're encountering issues because you're passing strings where arrays of `Competence` and `Aspect` objects are expected when defining your `Origin` enum constants. Let's correct that.

    You need to pass arrays of `Competence` and `Aspect` objects instead of strings. Here's how you can do it:

    ```java
    public enum Origin {
    Batra("Batra", new Competence[]{Competence.Admin}, new Aspect[]{new Aspect("ExampleAspect")});

    private String name;
    private Competence[] competences;
    private Aspect[] aspects;

    Origin(String name, Competence[] competences, Aspect[] aspects) {
    this.name = name;
    this.competences = competences;
    this.aspects = aspects;
    }
    }
    ```

    In this corrected version, `Competence.Admin` represents an instance of the `Competence` enum, and `new Aspect("ExampleAspect")` represents an instance of the `Aspect` class. Make sure to adjust the parameters accordingly based on your actual data.

    With these adjustments, you should be on the right path to successfully create instances of the `Origin` enum and progress with your personal project. If you encounter any further challenges or need help with your Java assignment, feel free to ask for help from various programming communities, assignment help platforms like ProgrammingHomworkHelp.com or online resources available for learning and troubleshooting, as there are many valuable resources out there to support your learning journey.
