Running a program with a package

Can any one tell me if i have saved the following file as test.mxml

If i run the program i get some errors.If we include a class in a package how should the program be run??

package {
import flash.display.Sprite;
开发者_Python百科import flash.media.*;
public class test  {

    public function Test() {
          //alerting some code
    }
}
}

You can either have a MXML class that would look something like this Test.mxml:

<?xml version="1.0" encoding="utf-8"?>
<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" 
xmlns:s="library://ns.adobe.com/flex/spark" 
xmlns:mx="library://ns.adobe.com/flex/mx" minWidth="955" minHeight="600"
creationComplete="application1_creationCompleteHandler(event)">
<fx:Script>
<![CDATA[
import mx.controls.Alert;
import mx.events.FlexEvent;
protected function application1_creationCompleteHandler(event:FlexEvent):void
{
   Alert.show("test");
}
]]>
</fx:Script>
</s:Application>

Or you can have a pure actionscript class that looks like this:

Test.as

package
{
import mx.controls.Alert;

  public class Test
  {
     public function Test()
     {
       Alert.show("Test");
     }
  }
}

Your problem might be the lower case "t" of your class name and the upper case "T" of its constructor. Otherwise it's not clear what you are asking.
