The following image is the graphical representation of the state machine for constructing Email object with the Step Builder pattern (mandatory values are marked purple and optional values are yellow): Rules of thumb for implementation: 1. Builder pattern aims to “Separate the construction of a complex object from its representation so that the same construction process can create different representations.” It is used to construct a complex object step by step and the final step will return the object. 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. However, the client Java API provided by Amazon is not so simple to interact with, so I decided to create a small wrapper around their API. What prompted me to use Amazon SES API is its price. Home is the final end product (object) that is to be returned as the output of the construction process. Cold drink could be either a coke or pepsi and will be packed in a bottle. Each creational step should return the next step (interface) in the chain. Since each step in a step builder specifies the next step in the return type, you can't re-use step interfaces very easily.
