各位大神，請問我這樣有沒有體現(xiàn)多態(tài)性？
package com.zp.duotai;
class ?Vehicle{
public void Function() {
// System.out.println("交通工具");
}
}
class Airplane extends Vehicle{
String name="飛機";
int number=500;
String way="air";
public void Function() {
System.out.println("交通工具:"+name+"，載客人數(shù)："+number+"人，運行方式："+way);
}
}
class Ship extends Vehicle{
String name="輪船";
int number=200;
String way="water";?
public void Function() {
System.out.println("交通工具:"+name+"，載客人數(shù)："+number+"人，運行方式："+way);
}
}
class Bus extends Vehicle{
String name="公交車";
int number=40;
String way="road";
public void Function() {
System.out.println("交通工具:"+name+"，載客人數(shù)："+number+"人，運行方式："+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();
}
}

我把你的代碼復(fù)制到eclipse運行public class jiaotonggongju這一行也會報錯啊
