I would have to say that interfaces are probably the most misunderstood Java language feature: what they are, and more importantly, why they are so powerful when used properly.

Also, while not specific to Java (or, for that matter, to OO languages specifically), the overall key design principles of model-view separation and model-data layer separation are frequently overlooked in beginning Java courses and texts.

Regards,

Jacquie

Another VERY FUNDAMENTAL concept that can really be tough for some folks to grasp is the notion of references: i.e., that an object is a chunk of memory; a reference variable is a symbolic name that maps (ultimately) to that chunk of memory; and, that different reference variables, in different scopes of a prgram, can be referencing the same chunk/object.

Many newer programmers began programming with "visual" languages, never having to struggle with pointers in C or memory addresses in an assembly language. Some of my best OO students are folks who've last programmed in Fortran!

Best,

J.
