Java constructor with large arguments or Java bean getter/setter approach

Question

I can\'t decide which approach is better for creating objects with a large number of fields (10+) (all mandatory) the constructor approach of the getter/setter. Constructor

Answer 1

This is pretty hard to answer in the abstract. What really needs to be done is to look at those ten parameters and see what they are. I see these as the key questions:

• Can some of them be combined into higher level "value" objects? For example, variables X and Y can be combined into Point. We had lots of situations like this within a cargo routing program where all fields were modeled as primitive strings. Introducing a few higher level concepts really helped make it readable.
• Can some of the parameters be "defaulted" to certain values?
• Are they really all independent, orthogonal concepts? I've worked on lots of systems and never seen this to be true. If not, there is some thinking to do about these.
