Basic classes hold per-object state. Production verification also needs class-level state, access control, parameterization, frozen constants and organized files.

Lesson	What it covers
Static Properties & Methods	One shared counter for the whole class, and the limits of static methods.
local, protected & Encapsulation	Who may see each member, and a checker that hides its expected queue.
Parameterized Classes	One template stamped into distinct checked types with separate statics.
Constants & Enums in Classes	Frozen per-object values, enum kind fields and one shared lookup table.
extern Methods & Class File Organization	Prototypes inside the class with bodies outside, plus the package library.

Check yourself A checker class needs a counter shared by every packet, an expected queue that outside code cannot touch, and one implementation that serves two packet types. Which feature supplies each need?

A static property counts across all objects. A local queue hides the expected list behind methods. A parameterized class serves both protocols as two distinct checked types.
