What are the difference between a Static class and a Singleton class?
- A Static class can have instance methods and properties, while a Singleton class can only have static methods and properties.
- A Static class can have multiple instances, while a Singleton class can have only one instance.
- A Static class does not maintain state, while a Singleton class maintains state for a single instance.
- A Static class is a class that cannot be instantiated, while a Singleton class can be instantiated only once.
A Static class is a class that cannot be instantiated and can only have static members. It is a sealed class, which means it cannot be inherited. A Singleton class is a design pattern that ensures a class has only one instance while providing a global point of access to this instance. It uses a private constructor and a static instance variable to ensure that only one instance can be created. Unlike a Static class, a Singleton class can have both static and instance members.
