When you use "new", you are creating a new instance of the object (in this case, a Choice object).

This is where the custom constructors (of the lesson) come into play. When you create a new instance of an object, the system will call the constructor method to know how to create the object. In this case, the constructor for a Choice object is the following:

public Choice(String text, int nextPage) {
    mText = text;
    mNextPage = nextPage;
}

So when he creates a Choice object (via the new statement), he provides data to be included in the object (the text and the ID for the next page).
