Builder Design Pattern
Type : Creational Design Pattern Summary Builder pattern is a Creational Design Pattern and solves the problem of creating complex objects or objects whose constructor needs many parameters. Details Considering a Class whose constructor has a number of parameters, we have to send all of them to instantiate an instance, which could be error prone and complex sometimes. Also if the constructor has some optional parameters or if we want to have some parameters to have fixed value, we might end up with a number or Constructors for the object. Builder pattern solves this problem by exposing a builder object which can have multiple methods based on different parameters. Example For our example we will consider a Class BlogObject which represents a Blog and has a number of fields. Some of the fields like, Tag, Summary etc are optional. Without Builder we might need to have a number of constructors for the Class. But with Builder we can create the instance of the Object easily a...
