It rare that I see good Java code, especially that written by junior developers. I think OO is a hard concept to get right. I know it took me years to master, and one of my epiphanies about OO design is that it's not always appropriate. Yes I can tell you the best OO approach to a problem, but I can also often tell you a better approach that isn't OO.
