Initializing final fields in Java

Question

I have a class with lots of final members which can be instantiated using one of two constructors. The constructors share some code, which is stored in a third constructor.

Answer 1

All you need to do is ensure that "two" gets initialized. In the first constructor, just add:

two = null;

unless there's some other value you'd like to give it in the event that only the first constructor is called.
