Ensures a class has only one instance and provides a global point of access to it.

Defines an interface for creating an object but lets subclasses decide which class to instantiate. Defers instantiation to subclasses.

Provides an interface for creating families of related objects without specifying their concrete classes.

Separates the construction of a complex object from its representation, allowing the same construction process to produce different results.

Creates new objects by cloning an existing instance, avoiding the cost of building from scratch.
