试题七（共 15 分）

阅读下列说明、图和Java代码，将应填入 （n） 处的字句写在答题纸的对应栏内。

[说明]

已知对某载客车辆(Car)进行类建模，如图 7-1所示，其中类 Engine 表示发动机引擎，类 Wheel 表示车轮，类 Body 表示车身，类 Driver 表示司机，类 Passenger 表示乘客。

[Java 代码]

class Body{ //此处代码省略 }; //车身类

class Passenger{ //此处代码省略 }; //乘客类

class Wheel{ //此处代码省略 }; //车轮类

class Driver{ //司机类

public String name; //表示第几路公交车司机

public Driver(String driverName){name = driverName;} //构造函数

};

class Engine{ //引擎类

public String engineNo; //引擎编号

public Engine(String engineNo){ this.engineNo = engineNo; } //构造函数

};

public class Car{ //汽车类

static final int (1) = 7; //定义最多载客数

static final int MAX_WHEELS = 5; //定义最多轮胎数

protected Engine engine;

protected Driver driver;

protected Body body = new Body();

protected Wheel[] wheels;

protected Passenger[] passengers;

public Car(Driver driver){ //构造函数

(2) .driver = driver;

engine = new Engine("TX6536 型号引擎");

wheels = new Wheel[MAX_WHEELS];

passengers = new Passenger[MAX_PASSENGERS];

for (int index = 0; index < MAX_WHEELS; index++){

wheels[index] = new Wheel();

}

for (int index = 0; index < MAX_PASSENGERS; index++){

passengers[index] = null;

}

}

int getPassengerNumber(){ //获取车上乘客数量

//此处代码省略

}

void getOnPassenger(Passenger aPassenger ){ //乘客上车

//此处代码省略

}

void run(){ //开车

if( (3) ){ System.out.println("司机尚未上车!"); return;}

//此处代码省略

}

public static void main(String args[]){

Driver driver = new Driver("第五路公交车司机");

Car car = new Car( (4) );

for (int index = 0 ; index < MAX_PASSENGERS; index ++)

car.getOnPassenger( (5) Passenger());

car.run();

}

}
