Suppose you have two classes A and B where B inherits from A. Suppose also that you have a variable V of type A. Now V can contain a reference to either an A object or a B object. So we can say that V's static (or compile time) type is A but its dynamic (or runtime) type could be either A or B depending on what kind of object has been assigned to it. For example: A V = new A(); // static and dynamic types of V are both A V = new B(); // dynamic type of V is now B
