Why interface methods can't be static in class that implements the interface?

Lets suppose I have code like this:

public interface JustAnInterface {
    void doSomething();
}

public class JustAnInterfaceImplementation implements JustAnInterface {

    @Override
    public static void doSomething() {

    }
}

Why does static doSomething() method shows the error "Method does not override method from its superclass"?
