Question: I have a method that names
something like this - public String doSmth()...
I do not need any Object for this method. Can I make it static?
Is it good idea to make all methods that do not use Objects static?
Answer: yes, I think so. It is bad idea to
create an instance of the class just to use one method without needing the
itself. Wasting of memory and CPU performance for further garbage collecting of
the Object that has not been used
