Daily Term: Singleton Pattern

Singleton Pattern

The Singleton Pattern ensures a class has only one instance and provides a global point of access to it. For example, a logging class might be a singleton to ensure all parts of an app write to the same log file. It’s implemented by making the constructor private and providing a static method to access the instance. Singletons simplify resource sharing, but they can make testing harder and introduce hidden dependencies.
