Singleton: Ensures that a class has only one instance and provides a global point of access to it. This is useful for managing shared resources like database connections or thread pools.Factory Method: Defines an interface for creating an object but lets subclasses decide which class to instantiate. This promotes loose coupling by eliminating the need to bind application-specific classes into the code.Abstract Factory: Provides an interface for creating families of related or dependent objects without specifying their concrete classes.Builder: Separates the construction of a complex object from its representation, allowing the same construction process to create different representations.Prototype: Permits the creation of new objects by copying an existing object (a prototype) rather than creating them from scratch.
