Final Class Assignment & Homework Help

Final classes can be used to prevent inheritance of a class, for security reasons. Best way is to declare final is for String variables, which is immutable.
Public final String s;
Writing a class as ‘final’ means, the code is secured and strong. Nobody can access or change your code, since the variables are constants in the class. In Java, items with the final modifier cannot be changed.
