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 variable that is set to a new Arraylist object reference.
%(Arraylist) The optional class name in parentheses denotes a Constructor. See "Usage notes," below, for more information about invoking a collection Constructor.

Usage notes

  • As described in "Using New or other Constructors", New can be invoked with no object, with an explicit class name, or with an object variable, even if that object is Null:

    %al = new %al = %(Arraylist of float):new %al = %al:new

    Note: As shown above, when explicitly indicating the class, both the collection and the item datatype must be specified just as they are on the collection variable's declaration:

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