O is for Object Oriented ActionScript

ActionScript is powerful, object oriented programming language. ActionScript and MXML are the languages of Flex.

ActionScript requires classes/interfaces to be declared in a package and the explicit import of used classes/interfaces that are not in the same package.

package packageName
{
  import another.packageName.*;
 
  public class ClassName extends SuperClassName implements InterfaceName
  {
     public ClassName()
     {
        // constructor
     }
  }
}
