Make Return Type an Interface – Problem with Initialization
I would like to make the return type of my method an interface rather than a class for similar reasons stated in c# List or IList, however I am having trouble figuring out how to initialize the interface to return it. I cannot use new IA()
and (IA) new A()
does not work as I cannot cast the result to B
.
issues about Spring initialization in different environment
I have some questions about spring’s initialization in different environment.
Initialize in Field, Constructor, or Argument
If I know what a field will be initialized to, should I initialize it in the field, constructor, or receive it as a parameter? I am asking about best practices. All three options effectively provide the same result. I am not considering what is happening behind the scenes, because I think it would be insignificant.

In C++, how to call an ‘init’ routine as a class is loaded?
I have a program that loads a bunch of “addons” (different meters that measure and display system values).
