I’m writing today to talk about something that I think is pretty cool — design patterns in code! Specifically, we’re going to cover the builder pattern, which I find myself using all the time when writing Android applications and sometimes when writing plain Java applications. Let’s setup a scenario: You have a class that has a constructor. You call it a <code>User</code> class. The constructor for this class takes in a <code>String firstName</code> and a <code>String lastName</code>. You write some awesome logic in this class and use it everywhere. You new it up all over your codebase because it’s just <strong>that</strong> good. You kick back and enjoy the good life, until you have another developer walk over to you and say <em>“Oh, hey. We need to add email address to the user class. And we’ll probably want to add phone number and mailing address, too.”</em> Crap.</p>
