各位大神，请问我这样有没有体现多态性？

package com.zp.duotai;

class  Vehicle{

public void Function() {

// System.out.println("交通工具");

}

}

class Airplane extends Vehicle{

String name="飞机";

int number=500;

String way="air";

public void Function() {

System.out.println("交通工具:"+name+"，载客人数："+number+"人，运行方式："+way);

}

}

class Ship extends Vehicle{

String name="轮船";

int number=200;

String way="water"; 

public void Function() {

System.out.println("交通工具:"+name+"，载客人数："+number+"人，运行方式："+way);

}

}

class Bus extends Vehicle{

String name="公交车";

int number=40;

String way="road";

public void Function() {

System.out.println("交通工具:"+name+"，载客人数："+number+"人，运行方式："+way);

}

}

public class jiaotonggongju {

public static void main(String[] args) {

Vehicle air = new Airplane();

Vehicle bus = new Bus();

Vehicle ship = new Ship();

air.Function();

bus.Function();

ship.Function();

}

}
