java

I have 10 instances of the class movie which I wish to add to an Arraylist named Catalogue1

in a class containing a main method I write the following

 ArrayList catalogue1= new ArrayList ()

   //the class movie is defined in another class
    Movie movie1= new Movie ()
   Movie movie2= new Movie ()

 Catalogue.Add (1, movie1)

What is wrong? Should I define somewhere what kind of Objects this arraylist named catalogue should contain?

Thank you in advance
