The pattern allows you to produce different types and representations of an object using the same construction code. The singleton pattern is the most famous among all the design patterns. Java has three types of design patterns: In that case it's used to store the state of an object into a memento object while anything can modify the original object and allows you to restore the old state by using the memento as a previous state of your object.

The singleton design pattern is a creational pattern, whose objective is to create only one instance of a class and to provide only one global access point to that object. Java has three types of design patterns: Let's discuss some categories of a behavioral design pattern. This design pattern is mainly used to construct a system where each request passes.

The decorator pattern uses composition in place of inheritance to extend the functionality of an object at runtime. These are mainly involved with the creation of objects. Details of each of the creational design patterns are listed below.
