    Default Simple enum question!

    Hi, im having some problems with adding an enum value to an object in an arraylist.

    I've highlighted the part that i can't get to work: rating.five (could not highlight the codesnip)
    mediaList.add(new Movie("title", 125, 2012, false, "Director", "path too hdd", rating.five, "HD", false, "Spanish", "Writer"));

    Enom code:
    public enum rating{one,two,three,four,five};
    private rating myRating;

    I tried importing Media.rating as well but without any luck, help is appreciated.

    Can you post an MCVE that demonstrates the problem you're talking about? What error are you getting?

    Super:
    package thiistest;
     
    public abstract class one {
     
    	public enum number{one,two}
    	private number myNumber;
    	public one(number myNumber) {
    		super();
    		this.myNumber = myNumber;
    	}
    	public number getMyNumber() {
    		return myNumber;
    	}
    	public void setMyNumber(number myNumber) {
    		this.myNumber = myNumber;
    	}
    	@Override
    	public String toString() {
    		return "one [myNumber=" + myNumber + "]"+toStringSpec();
    	}
     
    	public abstract String toStringSpec();
    }
    Sub:
    package thiistest;
     
    public class two extends one {
     
    	private String name;
     
    	public two(number myNumber, String name) {
    		super(myNumber);
    		this.name = name;
    	}
     
    	public String getName() {
    		return name;
    	}
     
    	public void setName(String name) {
    		this.name = name;
    	}
     
    	public String toStringSpec() {
    		return "two [name=" + name + "]";
    	}
     
    }

    Test:
    package thiistest;
     
    import java.util.ArrayList;
     
    import thiistest.one.number;
     
    public class tersfzdsafds {
     
    	ArrayList<one> foo = new ArrayList<one>();
     
    	public void addTest() {
    		foo.add(new two(number.one,"name"));
    	}
    }

    It works when i do it now however i noticed that "package thiistest;" is included tho the path is not included in the project i'm working in, why is that?

    I don't really know what you're asking. Where isn't the package included?

    If your actual program doesn't have packages, then your example shouldn't have them either. That's the whole point.

    You can't import classes or enums from the default package into another class, even if that other class is also in the default package. However, you can just use the class name to refer to it instead.
