 ### Part 6.1 - Create `People` class
 * Create a `People` class.
-	* The class should instantiate an `ArrayList` field of `Person` objects named `personList`.
+	* The class should instantiate a `List` field of `Person` objects named `personList`.
 	* The class should define a method named `add` which adds a `Person` to the `personList`.
 	* The class should define a method named `findById` which makes use of a `long id` parameter to return a `Person` object with the respective `id` field.
+	* The class should define a named `contains` which makes use of a `Person person` parameter to return `true` if the `personList` contains the respective `Person` object.
 	* The class should define a method named `remove` which makes use of a `Person person` parameter to remove a respective `Person` object.
 	* The class should define a method named `remove` which makes use of a `long id` parameter to remove a `Person` object with the respective `id` field.
-	* The class should define a method named `getCount` which returns the size of `personList`.
-	* The class should define a method named `getArray` which returns an array representation of the `personList` field.
 	* The class should define a named `removeAll` which clears our `personList` field.
+	* The class should define a method named `count` which returns the size of `personList`.
+	* The class should define a method named `toArray` which returns an array representation of the `personList` field.
+	* The class should implement `Iterable<E>` and define a method named `iterator` which makes use of the `personList` field to generate a new a `Iterator<E>`.
