Hi,

   I would like to know if the following can be done.

   I have a single class  "class A" which is extended by several classes.

I originally create a object which is an instance of  class A. |The
constructor for this class names in it arguments a string which is derived
from user interaction at run time.  Once a new instance of Class A is
created  I then want to create an instance of one of the child classes by
casting. which child class  I chose to  use is determined by one of the
previously mentioned user input.

Ok, can I create the instance of the required class with out using a switch
or if statement? ie can I specify the required class dynamically based on
the value previously mentioned user input.

in the statement  ClassName n = new ClassName();   I want to dynamically
substitute ClassName at run time.

Thanks in advance
Barry
