Create a custom class 261

Build a custom class

You’ll now build a new Product class with getter and setter methods and

create an object from the Product class.

1. Create an ActionScript file by selecting File > New > ActionScript File

(Not Flash Document). Save the document with the name Product.as.

2. Create a constructor for a Product class by creating a function called

Product that takes the arguments

id, prodName, and description:

function Product (id:Number, prodName:String,

description:String)

{}

In the constructor function, set the properties of the Product class equal

to the setter methods that you will create:

setID(id);

setProdName(prodName);

setDescription(description);

Surround the class keyword with the constructor function.

Declare each variable used in the class:

class Product

{

var id:Number;

var prodName:String;

var description:String

function Product (id:Number, prodName:String,

description:String)

{

setID(id);

setProdName(prodName);

setDescription(description);

}

Define getter and setter methods for each property of the class, as in the

following example.

Specify

Void as the return type for the setter methods, and indicate the

data type returned for the getter methods.

class Product

{

var id:Number;

var prodName:String;

var description:String
