Abstract Factory DesignPattern-1

Abstract Factory Design Pattern

  • In software development, a factory is the location in the code at which objects are constructed. 
  • The intent in employing the pattern is to insulate the creation of objects from their usage. This allows for new derived types to be introduced with no change to the code that uses the base class.
  • The essence of the Abstract Factory method Pattern is to "Provide an interface for creating families of related or dependent objects without specifying their concrete classes".
  • For Example:
    • Address Factory has no of factories like:
      • US Address Factory which implements the Address Interface.
      • French Address Factory which implements the Address interface.
      • Can have many more country specific factories….
  • When we create the French Address using the method implemented in the French Address Factory class it returns the Object reference to the Abstract class of Address.
  • The Abstract Address class holds the abstract method named get Country() which is implemented separately by each implementing class

Design Patterns (TID)

The pattern is an organised way of solving some specific class of problems. These patterns come in to the picture at analysis and high-level-design phase. The first step of applying one pattern to the code base is first to understand the find the vector of change in the code base. Next step is to isolate the things that are subject to change form the things that are not. That is adding a layer of abstraction to the code. The goal of design patterns is isolating the changes in your code. Understand Inheritance and Composition as a solution to a specific class of problems. Inheritance : - It allows you to express differences in behavior (that's the thing that changes) in objects that all have the same interface (that's what stays the same). Composition : - Composition can also be considered a pattern, since it allows you to change—dynamically or statically—the objects that implement your class, and thus the way that class works. Some principles of designing the c...

Primitive Obsession with Example

Primitive Obsession is the name of a code smell that occurs when we use primitive data types to represent domain ideas. For example, we use a string to represent a message or an integer to represent an amount of money. For Example: Code with Primitive Obsession // primitiveObsession.java public class primitiveObsession { public static void main ( String args []) { Integer [] cityPopulations = { 13000000 , // London 21903623 , // New York 12570000 , // Tokyo 1932763 , // Stockholm 1605602 , // Barcelona 4119190 // Sydney }; for ( Integer cityPopulation : cityPopulations ) { System . out . println ( cityPopulation ); } } } public class City { private final String name ; private final int population ; private final Continent continent ; public String getName () { return name ; } public int getPopulation () { return population ; } public Continent ge...
