whether express the Pharaoh and talk of the town a couple ?
------ For reference only -------------------------------------- -
theoretically can only show you this formula Pharaoh and talk of the town there is a common son , can not explain the couple .
Pharaoh classes can be built
public class PersonWang extends Person {
Parent parent ;/ / parent object which contains two people , his father, his mother
Child child ;/ / child object which contains two people , his father, his mother
Wife wife ;/ / wife object which contains a man , his wife
Job job ;/ / job object , place of work , nature , etc.
/ / Method: play ball
}

public class PersonWang extends Person {

Child child ;/ / child object which contains two people , his father, his mother

}
but also for old Wang class ? Do you want a few NEW Pharaoh ?
why there is no master shot ? Too simple ?
