**定义抽象的交通工具类：**

**定义交通工具保养的接口：**

interface Maintainable//定义Maintainable接口
    {
        public void maintenance();//定义抽象方法
    }

**定义卡车类，继承交通工具类、实现保养接口：**

class Truck extends Transportation implements Maintainable//定义Truck类，该类继承Transportation类，并实现Maintainable接口
    {
        public Truck()
        {
            super();
        }
        public Truck(String number,String model,String carrier)
        {
            super(number, model, carrier);//调父类中的元素
        }
        public void transport()
        {
            System.out.println("运输中......");
        }
        public void maintenance()
        {
            System.out.println("货物运输车辆保养完毕");
        }
    }

**定义GPS接口：**

interface GPS//定义GPS接口，包含定位功能
    {
            public String showCoordinate();
    }

**定义设备类，实现GPS接口：**

class Phone implements GPS//定义Phone类，并实现GPS接口
    {
        public String showCoordinate() {
            String location="193°45,48°5";
            return location;
        }
    }

**定义快递类：**

class Delivery//定义Delivery类
    {
        private String deliveryID;//快递单号
        private double weight;//货物重量
        public Delivery(String deliveryID,double weight)
        {
            this.deliveryID=deliveryID;
            this.weight=weight;
        }
        public String getDeliveryID()
        {
            return deliveryID;
        }
        public double getWeight(){
            return weight;
        }
    
        public void sendBefore()//sendBefore()，货物发送前
        {
            System.out.println("订单开始处理，仓库验货中......");
            System.out.println("货物重量："+getWeight()+"kg");
            System.out.println("货物检验完毕");
            System.out.println("货物填装完毕");
            System.out.println("货运人已通知");
            System.out.println("快递单号："+getDeliveryID());
         }
         public void send(Transportation t,GPS g)//send(t,g)方法，货物发送途中
         {
            System.out.println("货运人"+t.getCarrier()+"正在驾驶编号为"+t.getNumber()+"的"+t.getModel()+"发送货物");
            t.transport();
            System.out.println("货物当前的坐标为："+g.showCoordinate());
         }
         public void sendAfter(Transportation t)//sendAfter(t)方法,货物送达后
         {
            System.out.println("货物运输任务已完成!");
            System.out.println("货运人"+t.getCarrier()+"所驾驶的编号为"+t.getNumber()+"的"+t.getModel()+"已归还");
         }
    }

**定义测试类：**

public class test {
        public static void main(String[] args){
            Delivery del=new Delivery("HYX600235",763.8);//创建Delivery类的实例对象
            del.sendBefore();//调用Delivery类的sendBefore()方法
            System.out.println("========================================");
            Truck car=new Truck("Z025","沃尔玛","小韩");//创建Truck类的实例对象
            Phone p=new Phone();//创建Phone类的实例对象
            del.send(car,p);//调用Delivery类的send()方法
            System.out.println("========================================");
            del.sendAfter(car);//调用Delivery类的sendAfter()方法
            car.maintenance();//调用Truck类的maintenance()方法
        }
    }

**完整代码：**

abstract class Transportation{//定义抽象的Transportation类
        private String number;//交通工具的编号
        private String model;//交通工具的型号
        private String carrier;//交通工具的货运人
        public Transportation()
        {
            super();
