Later sometime including some nave users can easily get to know if two source files dont match by tallying the internal contents of the static functions and static variable as it will through the compilation error. WordPress Methods of only derived class can be made sealed with keyword sealed and override. DataLoader Syntax A class can contain multiple static blocks. If you have ever noticed, structs are sealed. Example: static vs readonly vs const A non-static method can access the static method, while a static method can access the non-static method only through the object of a class. It's rarely used like this in my experience, and your example is a good example of why. If a class or struct is marked as final then it becomes non inheritable and it cannot be used as base class/struct. It has different meanings based on the context.
