Can I add enums inside another enums using Java?

Can I add enums inside other enums? For example:

public enum Enum1 {
    VALUE1;
}
public enum Enum2 {
    Enum1,
    VALUE2;
}

Note: I already know that you can do it like this way:

public enum Action
{
   FOO,
   BAR;
   enum MOVE
   {
     UP,
     DOWN,
     LEFT,
     RIGHT 
   }
}

public enum Enum1 {
    VALUE1;
}
public enum Enum2 {
    Enum1, // Enum1 is just constant
    VALUE2;
}

It's possible, but Enum1 in Enum2 is just constant (without any dependency with Enum1 enum), however you can use something like this:

public enum Enum1 {
   VALUE1;
}

public enum Enum2 {
    VALUE1 (Enum1.VALUE1),
    VALUE2 (null);

    private final Enum1 enum1;

    Enum2(com.github.vedenin.services.image.filter.Enum1 enum1) {
        this.enum1 = enum1;
    }

    public Enum1 getEnum1() {
        return enum1;
    }
}
