builder vs factory pattern

Thanking You, Chamal. Unlike other creational patterns, Builder doesn’t require products to have a common interface. The builder pattern is a design pattern designed to provide a flexible solution to various object creation problems in object-oriented programming.The intent of the Builder design pattern is to separate the construction of a complex object from its representation. Builder design pattern also helps in minimizing the number of parameters in constructor and thus there is no need to pass in null for optional parameters to the constructor. Builder constructed: House@6d06d69c Advantages of Builder Design Pattern. Builder is a creational design pattern, which allows constructing complex objects step by step..
