Remember that static methods can't be overridden! This doesn't mean they
can't be redefined in a subclass, but redefining and overriding aren't the same thing.
Let's take a look at an example of a redefined (remember, not overridden), static
method:


class Animal
{
static void doStuff()
{
System.out.print("a ");
}
}
class Dog extends Animal
{
static void doStuff()
{
// it's a redefinition,
// not an override
System.out.print("d ");
}

public static void main(String [] args)
{
Animal [] a = {new Animal(), new Dog(), new Animal()};
for(int x = 0; x < a.length; x++)
a[x].doStuff();
// invoke the static method
}
}

/*
Running this code produces the output:
a a a
*/

Here redefining means that you declare a static method with the same signature as the supper class'. So the same method in super class is redefined in the subclass. As you already know that the static methods can't be overridden so this is what you can do if you want the static method to behave differently in the subclass. But remember you can't have the polymorphism since no overridden happens.
