1	Introduction: Why do we need Design Pattern? A bit of the history Good software practices and principles The Gang of Four (GoF) Overview of the Design Patterns Essential software engineering disciplines How patterns are documented? Class Abstract Class Interface Aggregation & Composition Multiplicity Association Role Attributes Operations and Methods Abstract Factory Builder Factory Method Prototype Singleton Adapter Bridge Composite Decorator Façade Flyweight Prox Chain of Responsibility Command Interpreter Iterator Mediator Memento Observer State Strategy Template Method Visitor Inheritance Polymorphism Abstract Classed and Methods Interfaces Access Modifiers	OO Terms.pdf Day1.zip University(Interface)
2	Creational Patterns: Creating Singleton Using a Static Method Exceptions and Instances Throwing the Exception Creating an Instance of the Class Providing a Global Point of Access to a Singleton Example in Java When to Use a Factory Method? Example in Java How a Simple Factory Works? Building the Simple Factory Using the Factory Consequences of Abstract Factory Example in Java How a Builder Works? Consequences of the Builder Pattern Example in Java Using the Prototype Deep Vs Shallow copy Cloning the Class Using the Prototype Pattern Dissimilar Classes with the Same Interface Prototype Managers Consequences of the Prototype Pattern Example in Java	Singleton FactoryMethod AbstractFactory Builder Prototype
3	Structural Patterns: Basic understanding of GC based system An Implementation of a Composite Doubly Linked Lists Consequences of the Composite Pattern A Simple Composite Example in Java Handling events in a Decorator Layout Considerations Multiple Decorators Decorators, Adapters, and Composites Example in Java Making an Adapter The Class Adapter Two-Way Adapters Pluggable Adapters Example in Java What Constitutes the Façade? Consequences of the Façade Example in Java Copy-on-Write Comparison with Related Patterns Example in Java Extending the Bridge Windows Forms as Bridges Consequences of the Bridge Pattern Example in Java Sharable Objects Copy-on-Write Objects Intrinsic and extrinsic Example in Java	Composite Decorator Façade Adapter Proxy Bridge Flyweight
4	Behavioural Patterns: Applicability Consequences of the Chain of Responsibility Example in Java Motivation Command Objects Building Command Objects Consequences of the Command Pattern Example in Java Motivation Applicability State machine Objects Used in Parsing Regular Expression Example in Java Motivation Consequences of the Iterator Pattern Iterators in Java collections classes Example in Java Interactions Between Controls Initialization of the System Mediators and Command Objects Consequences of the Mediator Pattern Single Interface Mediators Implementation Issues Example in Java Motivation Implementation Providing Undo Command Objects in the User Interface Example in Java	ChainOfResponsibility Command Interpreter Iterator Mediator Memento
5	“Don’t call me, I will call you” model Consequences of the Observer Pattern Event-Handler model in .NET Example in Java Switching Between States How the Mediator Interacts with the State Manager? Consequences of the State Pattern Example in Java Motivation The Context The Program Commands Example in Java Motivation Kinds of Methods in a Template Class Templates and Callbacks Summary and Consequences Example in Java Motivation When to Use the Visitor Pattern Visiting the Classes Visiting Several Classes Catch-All Operations with Visitors Double Dispatching Issue Traversing a Series of Classes Consequences of the Visitor Pattern Example in Java Overall structure of the design pattern catalogue Classification of relationships Categories of relationships Modifying relationships and design patterns	Observer State Strategy TemplateMethod Visitor
