Share resources among siblings

Question

I am looking for a method to share resources among siblings. For example, if the parent class has a File handler, is there a way in which I need to open and close a file only once.

Seems like a simple problem but I can't figure it out. I know I can pass the resources as parameters but is there a more elegant way ?

Answer 1

You could have the file handler be a static variable within the parent class. Than when you call the parent constructor of the the class, you would get the current instance of the file handler.
