Today, I would like to discuss another behavioral design pattern called the Memento Design Pattern which is used to restore the state of an object to a previous state.

statestorage and retrieval capabilities*. *The Memento object is _immutable _in general. The object holds the internal state of the Originator and allows it to restore it.
To understand the Memento Design Pattern let's take the example of the *Employee *class storing and retrieving its state using *EmployeeMemento *class.
In this blog, we will discuss Proxy Design Pattern, its example, and how it is different from the other design patterns. But, it’s important to have an understanding of the design patterns first. You can refer here.

Why do we need Design Patterns? Structure of Design Patterns. Types of Design Patterns. Creational Design Patterns. Factory Design Pattern. Overview of Design Patterns
This post looks at how to use the composite design pattern in Java, specifically the objects used in the pattern: component, composite, leaf, and client.
The Visitor design pattern lets us separate algorithms from the objects on which they operate. See how to implement it to follow the open/closed principle.
