This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread 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?
