Category: Software Design
Software design is based on the software requirements specification, designing the overall structure of the software system, dividing functional modules, determining the implementation algorithm of each module, and writing specific codes according to the functions determined in the requirements analysis stage to form a specific software design plan. Software design abstracts many things and problems, and abstracts them at different levels and angles. Decomposing a problem or thing and modularizing it makes it easy to solve the problem. The finer the decomposition, the greater the number of modules. Its side effect is to make the designer consider more coupling between modules

Inheritance – Why is this class considered to be the ultimate?
I tried to inherit the following type, but the compiler says it is final.
class Dice(private var side: Int)
