10,389 PointsIf we set the class variables as readonly, how come we are allowed to send arguments to it?
How come we can send arguments to it and set the value, but only THEN are we not allowed to change it? I don't see why we can assign values to it through arguments if it's already read only.

230,688 PointsI think you're confusing "readonly" with "constant". A "readonly" is intentionally designed to be set during object construction, but then not changed afterwards.
If the value is already known at compile time, you can use a "const" instead to create something that cannot be changed at any time.
