The override part is a comment. It means that the routine exists already in your class or parent(s) class and that you have decided to do it differently from the already implemented code. In other words, you have created a new class derived from an existing class. The existing class or one of its parent classes has implemented a function. You want to change the behaviour of that funciton so you override it by creating the same function in your class. Possibly I am not sure, but the keyword might also check your function parameters and return class to ensure that you are correctly matching the existing function as a check. Said another way, there exists a class called Foo and you derive from it with a class called MyFoo. Foo implements a routine called void doIt(int a); You want to override it. In eclipse, you type doI - and then ctrl-space and it auto-completes to the function signature with empty brackets and the @override keyword. Somewhere along the way, you change the funciton parameter to a float, but you leave the @override keyword there. As far as the compiler goes, this is legal, but with the override syntax there the compiler will flag that the routine is not really overriden since doIt() requires a int parameter and not a float. -- John F.
