      • When am I supposed to use static classes I don't know. My thinking is that if I want to create multiple objects of a class then I do not want the class to be static. But if I only want to use one instance of the class, then it doesn't matter if the class is static or not Is this correct thinking If it isn't, then please explain to me how I should think about this. Big thanks!
