what is the difference between the static functions and virtual functions

static function able to be called without creating object first.


class a;
  virtual function print();
    $display("this is a");
  endfunction
endclass

class b extends a;
  virtual function print();
    $display("this is b");
  endfunction
endclass

initial begin
  a a_h;
  b b_h = new();
  a_h = b_h;
  a_h.print(); // a handle point to b object, and print "this is b" because of virtual
end
