Bus:

private float price;
   private Driver[] drivers;

   public Bus (int number,String line,float price,int driverCount) {
       this.number =number ;
       this.line =line;
       this.price=price;
       drivers=new Driver[driverCount];
   }

   public int getNumber() {
       return number;
   }
   public void setNumber(int number) {
       this.number = number;
   }
   public String getLine() {
       return line;
   }
   public void setLine(String line) {
       this.line = line;
   }
   public float getPrice() {

       return price;
   }
   public void setPrice(float price) {
       if(price>Passenger.getMoney)
       {
       System.out.println("没钱请下车");
       }
       else
       {
           System.out.println("上车请刷卡");
       }
       this.price = price;
   }
   //增加司机
   public void addDriver(Driver driver ) {
       for (int i=0;i<drivers.length ;i++)
       {
           if (drivers[i]==null)
           {
               drivers[i]=driver;
           }
       }
   }

}

Driver:

public class Driver extends People //继承people的属性
{

private String serial;

   public Driver (String name,String sex,String serial ) {
       super(name, sex);
   }

   public String getSerial() {
       return serial;
   }

   public void setSerial(String serial) {
       this.serial = serial;
   }
}

Passenger: //继承people的属性

public class Passenger extends People{
public static final float getMoney = 0;
private float money;

   public Passenger (String name,String sex,float money) {
       super(name, sex);
   }

   public float getMoney() {
       return money;
   }
   public void setMoney(float money) {
       this.money = money;
   }

}

People:

public class People {
   private String name;
   private String sex;
   public void setName(String name) {
       this.name = name;
   }
   public String getName() {
       return name;
   }
   public void setSex(String sex) {
       this.sex = sex;
   }
   public String getSex() {
       return sex;
   }
   public People(String name,String sex)
   {
       this.name=name;
       this.sex=sex;
   }
}
