Class - a simple question

I am starting to learn coding the class… I tried to declare a movieclip variable in a class file. But it shows an error.


class findXY 
{
 
 public var a:MovieClip=new Movieclip();
 function findXY()
 {
  
 }
 
}
 

in flash i have


import findXY;
var myVar:findXY=new findXY();

The error message I get while running the movie is

Line 3: There is no method with the name ‘Movieclip’.
public var a:MovieClip=new Movieclip();
Total ActionScript Errors: 1 Reported Errors: 1

Where is the problem ?
