static method cannot be overriden to non-static.so static
method can be overriden to static.
the above example is true in static way
e.g.

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
Some case:
in the subclass Dog, if the method dostuff() is not
static,it will be compile time error in the above code
block .
