Class Objects

   <source lang="java">

package {

 import flash.system.*;
 import flash.display.Sprite;
 public class Main extends Sprite{
   public function Main(){
     var vp = MyClass;
     var pet = new vp();
   }
 }

}

 class MyClass {
   private var pet;
   public function MyClass (  ) {
      trace("constructor");
   }
 }
       </source>
   
  

Convert class to the more general type without writing any explicit code.

   <source lang="java">

package{

 import flash.display.Sprite;
 import flash.geom.Rectangle;
 public class Main extends Sprite{
   public function Main(){
       var square:Rectangle = new Rectangle();
       var array:Array = ["hello", "world"];
       var obj:Object;
       while (obj = array.shift())
       {
           trace(obj);
       }
       
       
       var str:String = "";
       if (!str) str = "Default";
       trace(str); //Default
       
       for (var i:int = 1; i < 4; i++)
       {
           trace(i, (i % 2)? "odd" : "even");
       }
   }
 }

}

       </source>
   
  

Define a class

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){
       var crTest:Car = new Car();
       trace(crTest.make);  // Displays: undefined
       crTest.make = "Old";
       trace(crTest.make);  // Displays: Olds

   }
 }

} class Car {

 private var _sMake:String;
 public function get make():String {
   return _sMake;
 }
 public function set make(sMake:String):void {
   _sMake = sMake;
 }

}

       </source>
   
  

Define class with properties

   <source lang="java">

package{

 import flash.display.Sprite;
 
 public class Main extends Sprite{
   public function Main(){

   }
 }

} class Car {

 private var _sMake:String;
 public function get make():String {
   trace("Getting the value...");
   return _sMake;
 }
 public function set make(sMake:String):void {
   trace("Setting the value...");
   _sMake = sMake;
 }

}

       </source>
