This week's giveaway is in the EJB and other Java EE Technologies forum. We're giving away four copies of EJB 3 in Action and have Debu Panda, Reza Rahman, Ryan Cuprak, and Michael Remijan on-line! See this thread for details.
I was reading about this online. A class that directly accesses member fields of another class, exhibits HIGH COUPLING. When changing an implementation of a class, does not effect classes that use it, exhibits LOW COUPLING.
Can someone give me an example of a HighCoupling scenario and how Low coupling can be achieved in that case?
