Static Class: A class that only contains static components and no instance components is referred to as a static class. Singleton Class: It is a class which does not allow you to create multiple instances.
A static method belongs to the class itself and a non-static (aka instance) method belongs to each object that is generated from that class. If your method does something that doesn't depend on the individual characteristics of its class, make it static (it will make the program's footprint smaller).
