additional new book is generated (creating a new instance). Oh,my god! you will re-aspire to process-oriented program design approach, yearning to have global variables of the era. However, this situation does not occur because you have another variable type in C #: a static variable. It is like a global variable in a class that holds the public information for a class, and all instances (objects) of that class share the value.Static variables are declared in the following way:[Access modifier]

things in real world terms. in other words they describe an object. an object, or instance, of a class is an actual "living, breathing" structure of that class. let's say we want to describe a bicycle. A proper class of a bicycle might have the variables $ pedals, $ chain, $ front wheel, $ rear wheel, $ brakes, and $ handle_bars. functions of the bicycle wocould include Stop (), Accelerate (), Coast (), TurnLeft () and TurnRight (). you can think of your script as the entity operating that
to the singleton pattern, we have provided enough information, factory class, and static methods inside the factory class. In the static method, the object instance that needs to be created in new is done. Of course, considering the second question above, according to the parameters of static method of factory class, we can make a simple judgment. Tube you with If. else.. or switch. Case: It's good to be able to quickly and efficiently decide which class to create. Finally, be sure to remember
