Hi,

If the compiler can resolve the binding at the compile time only then such a binding is called Static Binding or Early Binding. All the instance method calls are always resolved at runtime, but all the static method calls are resolved at compile time itself and hence we have static binding for static method calls. Because static methods are class methods and hence they can be accessed using the class name itself (in fact they are encourgaed to be used using their corresponding class names only and not by using the object references) and therefore access to them is required to be resolved during compile time only using the compile time type information. That's the reason why static methods can not actually be overriden.

Thanks.
