Hi,
How can you make sure that subclasses cannot override a method.
In the java world, the 'final' keyword is used.



- thanks
 
In order to override a method it has to be marked virtual
in the base class. If you don't want it overridden,
don't mark it virtual.

If you're overriding a virtual method and you don't want
it overriden in your subclasses, mark it sealed.
 
This may help.

2) All Methods are Not Virtual By Default. All Members are Private by
Default.

In Java, all methods are virtual by default and can be overridden. Not
so
in C#. You must explicitly declare a method virtual if you want it to
allow
it to be overridden. You also cannot implicitly override or hide a
virtual
method, but must explicitly use the override or new keyword. In Java,
members have package level access by default. In C# all members are
private by default.

Jeff
