Static means one per class, not one for each object no matter how many instance of a class might exist. This means that you can use them without creating an instance of a class. Static methods are implicitly final, because overriding is done based on the type of the object and static methods are attached to a class, not an object. A static method in a superclass can be shadowed by another static method in a sub class, as long as the original method was not declared final.
However, you can't override a static method with a non static method. In other words, you can't change a static method into an instance method of a subclass.
