Object oriented programming, though not the Java BeanCakeFactoryFactoryInterfaceProvider approach. It isn't exactly Java's fault though, it is just common there - but there are exceptions (see Swing vs SWT, with the latter having a much simpler API or LWJGL which has a very simple API itself). Also i don't really do the whole patterns thing (unless accidentally) nor all the acronyms (i don't care about things like LSP, SOLID, etc, i mainly keep related things together and use inheritance for specialization). Of course i don't do OOP for the sake of OOP, i stick with simple procedural code where it makes sense, but for some things (e.g. GUIs) other approaches feel like trying to shove a square peg through a round hole.
