Static Methods and Properties :

• Static methods, also called class methods, are methods that are declared with the static keyword.
• Static methods, which are attached to a class rather than to an instance of a class.
• Static methods, are useful for encapsulating functionality that affects something other than the state of an individual instance.
• Static methods can be accessed only through a class and not through an instance of the class.
• We cannot use the keywords this or super within the body of a static method.
• [reason : Both the this reference and the super reference have meaning only within the context of an instance method.]
• Static properties are not inherited by subclasses. This means that static properties cannot be accessed through an instance of a subclass. A static property can be accessed only through the class object on which it is defined.
• Although static properties are not inherited, they are within the scope chain of the class that defines them and any subclass of that class.

I did a small Example on Static method defined in Action Script class.
