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.
Make the class of the single instance responsible for access and initialization on first use. The single instance is a private static attribute. The accessor function is a public static method. The Singleton pattern ensures that a class has only one instance and provides a global point of access to that instance. It is named after the singleton set, which is defined to be a set containing one element. The office of the President of the United States is a Singleton.
