I have a class with 20+ class variables, mostly String and Date types.
The constructor of this class receives a String which is raw text that

variables.
It does not seem right to me to perform this operation in the
constructor. I looked into the GoF creational design patterns but can't
seem to be able to find the appropriate solution for this problem.
Neither Factory Method nor Abstract Factory look like the right thing to
do (at least to me).
Can anybody suggest a good alternative to doing the parsing in the
constructor?
20 arguments of String / 1 argument of String[]
The real question should be, why are you parsing the string? Is it not
possible to specify this as several strings?
If you must parse, then perhaps using the Builder pattern is more
appropriate.
I am parsing the string because we have no control over it. It is a
bunch of text that we receive from a 3rd-party provider.
If code outside of your control will call your code with a long string
and you code need the separate parts, then obviously you need to parse.
And I can not see why parsing in constructor should be worse
than parsing so many other places (well maybe exceptions ...).
