How to convert values to HashSet directly

Question

I'm making a constructor that takes a HashSet as a parameter. How would you pass values directly on the constructor?

E.g.

```
class A { A(int x, HashSet<int> y) {} }

A a = new A(5, /*how to pass 6 and 7 directly?*/);
```

~ swim ~ (not available on messanger) Thanks for making it clear that you can only pass objects in a HashSet. I didn't know that.

Actually I've found another answer.

A a = new A(5, new HashSet<>(Arrays.asList(6, 7)));

My goal was just to make it so that you don't have to declare a collection.

Thanks for your answer
