One thing I love about builders, besides the sibling replies, is that builders force users to explicitly name the arguments. Passing args to a constructor/method/whatever with implicit argument ordering can be error-prone in certain situations (multiple adjacent args with the same type). c = Class(firstName, lastname) // are these passed in the right order? c = Class(lastName=firstName, firstName=lastName) // obviously incorrect Especially when you're using other magic like auto-generating constructors based on fields (as with Lombok)...then rearranging two String fields can subtly break things with no compiler errors!
