This question have a bug

enum SIZE
{
TALL, JUMBO, GRANDE;
}

class CoffeeMug
{

public static void main(String[] args)
{
var hs = new HashSet<SIZE>();
hs.add(SIZE.TALL); hs.add(SIZE.JUMBO); hs.add(SIZE.GRANDE);
hs.add(SIZE.TALL); hs.add(SIZE.TALL); hs.add(SIZE.JUMBO);
for(SIZE s : hs) System.out.print(s+" ");
}
}

This is set, should print all elements without duplicate.
Simulator give me a "right" answer that it should print this set with duplicate items.
I checked this code in compiler.
Compiler return me that it sholud print only not duplicate items.
Please fix

You are right. The given explanation is correct but two options have been set as correct by mistake.
Only option 3 should be set as the correct option. Fixed.
thank you for your feedback!
