Re: how to stop the subclass from overriding a method.

It makes more sense in java. Let me prove my point with an example.

 public final String  format (Object  obj) {
     return format(obj, new StringBuffer (), new FieldPosition 
(0)).toString();
 }

 public abstract StringBuffer  format(Object  obj,
                    StringBuffer  toAppendTo,
                    FieldPosition  pos);

Java doesn't provide the faicility of multiple arguments. Hence one will 
have to resort to method overloading. But, all the first method is doing 
is create two objects and calling the second method. Hence there is no 
point in leaving this method free to be played around with.

Also I believe in the web programming arena security concerns 
necessitate the surity that coe won't be dynamically changed.

Hope I am not preaching the prophet.
