class declaration

[Former Member]

hi all

can classes be both final and abstract?

Hi,

In SAP Final Class Means that class can not be inherited by any Child Class.

There is no such Abstract class in Sap

Hi,

you can define a class as abstract AND final in ABAP OO, but it makes no sense I think.

To do this means at least that you could only use as 'static' defined class components.

You can't set an instance method static and final at the same time !

Hi Olaf,

that was an intersting thing you pointed out.

But I still fail to justify allowing a class that is both abstract and final.

The usage that you mentioned should be actually served by an interface.

I also noted that the syntax check allows a class to be both final and abstract although an abstract method may be defined in it. This is again meaningless.
