These design patterns are all about class instantiation. This pattern can be further divided into class-creation patterns and object-creational patterns. While class-creation patterns use inheritance effectively in the instantiation process, object-creation patterns use delegation effectively to get the job done.;
***: <b>1. Abstract Factory</b>:

Creates an instance of several families of classes;
***: <b>2. Builder</b>:

Separates object construction from its representation;
***: <b>3. Factory Method</b>:

Creates an instance of several derived classes;

Avoid expensive acquisition and release of resources by recycling objects that are no longer in use;

A class of which only a single instance can exist;

These design patterns are all about Class and Object composition. Structural class-creation patterns use inheritance to compose interfaces. Structural object-patterns define ways to compose objects to obtain new functionality.;
***: <b>1. Adapter</b>:

Match interfaces of different classes;

Separates an object’s interface from its implementation;

A tree structure of simple and composite objects;

Add responsibilities to objects dynamically;

A single class that represents an entire subsystem;

A fine-grained instance used for efficient sharing;

Restricts accessor/mutator access;
***: <b>8. Proxy</b>:

An object representing another object;
**: <b>3. Behavioral design patterns</b>:

These design patterns are all about Class's objects communication. Behavioral patterns are those patterns that are most specifically concerned with communication between objects.;
***: <b>1. Chain of responsibility</b>:

A way of passing a request between a chain of objects;

Encapsulate a command request as an object;

A way to include language elements in a program;

Alter an object's behavior when its state changes;
