Given that object orientation underpins the Java language, it would be expected that anyone using Java would also know about OO. In one sense this is true, but there is more to effective modern object-oriented development than just creating a few objects and calling a few methods.
Many developers working in Java have not had the opportunity or exposure to effective object-oriented practice that would allow them to avoid common design pitfalls and to make more effective use of the language.
Although object orientation is far from being a new approach (think Sergeant Pepper), and it's also far from being obscure, its mainstream adoption by programmers and programming languages alike is not always as effective as it could be, and sometimes the results can be less than desirable (to put it politely). This session aims to put a number of concepts many developers may be unsure of on a firmer footing, highlighting common pitfalls in OO practice -- such as abuse of inheritance, simplistic getter/setter interfaces, patternitis, use of singleton objects -- and emphasising techniques that promote an easier life -- such as loose coupling, unit testability, pattern-based design thinking, incremental and sufficient design.
