Although I am aware of what a final class is, I am curious about how and when it is actually necessary.
final class Foo extends Bar
echo 'John Doe';
If I've got it right, "final" allows it to extend "Foo.".
Can somebody tell me when and why to use the word "final"? I.e., is there any justification for not extending a class?
It would be useful to construct a class that extends "Bar" if, for instance, classes "Foo" and "Bar" are missing some features.
