3.16. final Classes

Similar to final methods, you can also define a class as final. Doing so disallows inheriting from this class. The following code does not work:

 final class MyBaseClass {     ... } class MyConcreteClass extends MyBaseClass {     ... } 

MyBaseClass has been declared as final; MyConcreteClass may not extend it and, therefore, execution of the script fails.
