Can you elaborate a little more on the question? All object creation is done through constructors. If no constructor is specified, the compiler will supply a default empty constructor that basically does nothing. If you wish to provide info that initializes some values in the object when it's created, you provide a constructor for those parameters and initialize those values in that constructor.

Do you think that user of your application will be interested in reading your code and seting all variables by him self? Or do you think all variables are always initialized?
