Create a new Arraylist object (Arraylist class)


This method returns a new instance of an Arraylist.

Syntax

%al = [%(Arraylist Of itemType):]New

Syntax terms

%al An Arraylist object that is set to a new Arraylist object reference.
%(Arraylist) Either a parenthesized class name, as in %(Arraylist of float), or a non-parenthesized variable in the class, as in %al.

Usage notes

  • New is a constructor and as such can be called with no method object, with an explicit class name, or with an object variable, even if that object is null:
        %arrayl = new
        %arrayl = %(Arraylist):new
        %arrayl = %arrayl:new
    

    Note: When using the second of these syntax options of New, which explicitly indicates the class, both the collection and item datatypes must be specified just as they are on the collection variable's declaration:

        %arrayl  is collection Arraylist of longstring
        %arrayl  = %(Arraylist of longstring):new
