练习的代码，能修改更好吗？是否有冗余或更好的方法。

源自：10-1 Java 中的多态

这个是父类：

package com.imooc;

public class Transportation {

public String name;

public String space;

public int num;

public void getWay(){

}

这是其中一个子类：

package com.imooc;

public class Bike extends Transportation {

public String name = "Bike";

public String space = "陆地";

public int num = 2;

public void getWay(){

System.out.println(name+"的运输方式:"+ space+",运输人数："+num);

}

这是main函数：

package com.imooc;

public class Initial {

public static void main(String[] args) {

// TODO Auto-generated method stub

Transportation bike = new Bike();

bike.getWay();

Transportation bus = new Bus();

bus.getWay();

Transportation car = new Car();

car.getWay();

Transportation plane = new Plane();

plane.getWay();

Transportation ship = new Ship();

ship.getWay();

}
