### Class Instantiation Exercise

#### Given the following class definition, which statements will instantiate an object of this class? Choose all that apply.

```java
class Restaurant {
    private String name;
    private int rating;

    public Restaurant() {
        this.name = "no name";
        this.rating = 0;
    }

    public Restaurant(String initName, int initRating) {
        this.name = initName;
        this.rating = initRating;
    }
}
```

#### Options:

- [ ] none of these
- [ ] new Restaurant rest = Restaurant();
- [ ] Restaurant rr = new Restaurant("Chili's");
- [ ] Restaurant diner = new Restaurant(3, "Taco Bell");
- [ ] new Restaurant diner = Restaurant();
- [ ] Restaurant chillis = new Restaurant();
- [ ] String rest = new Restaurant("Chili's", 3);
- [ ] Restaurant fastFood = new Restaurant("Taco Bell", 3);
- [ ] new fastFood = Restaurant("Taco Bell", 3);
- [ ] int rr = new Restaurant();

### Explanation of Diagram:

There are no diagrams in this exercise. The question requires you to analyze given statements in Java to determine which ones correctly instantiate objects of the `Restaurant` class.

Each statement should be evaluated based on whether it follows the syntax and rules for object creation in Java, specifically targeting the `Restaurant` class definition provided.
