Answer 1

  //assumption: this method is adding a player into database and returns generated player id
    //Here player is object of class Player 
    public int addPlayer(Player player){
            int player_id;  //variable to store generated ID
            Session session = sessionFactory.openSession();
            session.beginTransaction();
            session.persist(player);  //adding player
            player_id=player.getplayer_id();  //getplayer_id is the getter method for the variable player_id
            session. getTransaction().commit();
            session.close();
            return player_id;
    }
