Vectors can only store objects so you always need to cast when you take the object out of the vector. Arrays can be created to hold a specific type of object (Button[] b = new Button[10] . Arrays are almost always faster than vectors. Vectors are synchronized.

It is sorta covered in the JavaRanch Style Guide.
