Object in array list

Question

Is it possible that object can be store in array list.
package{
// Importing object from flash libary
    import flash.text.TextField;
    import flash.display.Sprite;
// Creating class
     public class Show extends Sprite {
     //Attribute
    private var txt:Array = new Array();
     // Constructor 
       function Show()
               txt[0]:TextField =  new TextField();
                 addChild(txt[0]);
                 txt[0].width=320;
                 txt[0].height=25;
                 txt[0].x=0;
                 txt[0].y=0;
                 txt[0].border=true;
               txt[0].text="nepalikto";
Error
Description : Label must be a simple identifier
Location : Above orange textcolor line

Not sure if this all is 100% technically correct but:
You only use datatyping if you actually create a variable. Like:
var myArray:Array = new Array();
if you do not declare the var with the var keyword, you can't use datatyping either.
// this is wrong
myArray:Array = new Array()
It is good practice to use datatyping whenever possible since it can help you debug an application:
Flash finds the possible errors in code where one variable contains different datatypes at different times which can be confusing
Flash helps with the codecompletion feature once a variable is typed so there's less chance of typos.
The items in the array, unlike CS4's new Vector datatype aren't typed. Probably has some memory usage reason in the onderlying C++ code but I'm not sure. If you have CS4 you could possibly use:
var txt:Vector.<TextField> = new Vector.<TextField>();
To tell you the truth I haven't used the CS4 Vector Datatype so I'm not sure if aside from faster code execution there's errorcheckings on it's contents like mentioned above.
Hope this helps some
