# What Do Two Question Marks in a Row in a Ternary Clause Mean?

It is simply a nested ternary statement. Clearer by adding parentheses:

```
number == null ? (required ? 1 : 2) : 3;
```

what would the inputs need to be for 2 to be returned?

`number = null`

and `required = false`

This is why it’s always a good idea to explicitly add parentheses, so the intent is clear at a glance :

```
Integer val = number == null ? (required ? 1 : 2) : 3;
```
