import java.util.List;

public interface OlderMapper {

    void addOlder(Older older);

    void deleteByname(String name);

    Older Findbyname(String name);

    List<Older> Findbytwo(Older older);

    int updateOlder(Older older);

    List<Older> selectAll();

    Older Findbyage(int age);
}
