This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
a) My doubt is all these 4 methods does not make use of class variables, so can i make all these 4 methods static?
b) Usually i never see in any application they make these static my question is when do we make methods static?
