编写一个Java应用程序，设计一个汽车类Vehicle，包含的属性有车轮个数wheels和车重weight。小车类Car是Vehicle的子类，其中包含的属性有载人数loader。卡车类Truck是Car类的子类，其中包含的属性有载重量payload。每个类都有构造方法和输出相关数据的方法。最后，写一个测试类来测试这些类的功能。

class Vehicle{
   private int wheel;
   private double weight;

   public Vehicle() {

   }
   public Vehicle(int wheel, double weight) {

       this.wheel = wheel;
       this.weight = weight;
   }
   public int getWheel() {
       return wheel;
   }
   public void setWheel(int wheel) {
       this.wheel = wheel;
   }
   public double getWeight() {
       return weight;
   }
   public void setWeight(double weight) {
       this.weight = weight;
   }
   public void getInfo () {
       System.out.println("车的轮子为："+ wheel + ", 车重为："+ weight);
   }
}
class Car extends Vehicle{
   private int loader;

   public int getLoader() {
       return loader;
   }

   public void setLodar(int loader) {
       this.loader = loader;
   }
   public void getInfo() {
       System.out.println("车的轮子为："+ getWheel() + ", 车重为："+ getWeight () +"载人数量为：" + loader);
   }
}
class Truck extends Car{
   private double payload;

   public double getPayload() {
       return payload;
   }

   public void setPayload(double payload) {
       this.payload = payload;
   }
   public void getInfo () {
       System.out.println("车的轮子为：" + getWheel()+ ", 车重为："+ getWeight () +"载人数量为：" + getLoader()+ ", 车的载重量为：" + payload);
   }
}
public class Demo3 {
public static void main(String[] args) {
   Car car = new Car();
   car.setWheel(4);
   car.setWeight(23.6);
   car.setLodar(12);
   car.getInfo();
   Truck truck = new Truck();
   truck.setWheel(8);
   truck.setWeight(45.7);
   truck.setLodar(2);
   truck.setPayload(50.6);
   truck.getInfo();

}
