I am struggling with EnumSet as it surprisingly doesn&#39;t have a simple constructor and its methods doesn&#39;t like null values.

What I came up with:
`EnumSet&lt;MyClass&gt; x = EnumSet.copyOf(Collections.&lt;MyClass&gt;emptySet());`

Which somewhat works but doesn&#39;t seem right to me.

How to create empty EnumSet?

I have the following example:

    import java.util.EnumSet;
    import java.util.Iterator;
    
    public class SizeSet {
        
        public static void main(String[] args) {
            EnumSet largeSize = EnumSet.of(Size.XL,Size.XXL,Size.XXXL);
            for(Iterator it = largeSize.iterator();it.hasNext();){
                Size size = (Size)it.next();
                System.out.println(size);
            }
        }
    }
    
    
    enum Size {
      S, M, L, XL, XXL, XXXL;
    
    }

In this code I can understand that the Enum creates an Enum type of Sizes.

My question is: is `largeSize` an object of EnumSet type? What does it really mean? I really want to understand it better.
