网购已成为人民生活的重要组成部分,当人们在购物网站中下订单后,订单中的货物就会在经过一系列的流程后,送到客户手中。而在送货其间,物流管理人员可以在系统中查看所有物品的物流信息。编写一个模拟物流快递系统的程序,模拟后台系统处理货物的过程。
思路1)定义交通工具抽象类(jiaotonggongju),包含运输工具类型(leixing),承运商信息(chengyunshang),交通工具编号(num)
2)定义交通工具子类(jtgjzilei),包含运输工具类型(leixing),承运商信息(chengyunshang),交通工具编号(num),继承交通工具抽象父类,并对交通工具抽象类进行重写,
3)定义快递属性类和抽象方法,快递属性类(kuaidi),包含快递重量(weight),快递单号(ID),发货地点(place),抽象方法包含运送前,运送中,运送后。
4)定义测视类,通过调用交通工具子类、快递属性类、抽象方法和scanner函数,完成整个物流模拟快递系统的设计。
代码//定义交通工具类(类型、承运商、号码) package project1; import java.security.PublicKey; public abstract class jiaotonggongju { private String leixing; private String chengyunshang; private String num; public jiaotonggongju() { } public jiaotonggongju(String leixing,String chengyunshang,String num){ super(); this.leixing=leixing; this.chengyunshang=chengyunshang; this.num=num; } public abstract void gongju(); public String getNum() { return num; } public void setNum(String num) { this.num=num; } public String getLeixing() { return leixing; } public void setLeixing(String leixing) { this.leixing=leixing; } public String getChengyunshang() { return chengyunshang; } public void setChengyunshang(String chengyunshang) { this.chengyunshang=chengyunshang; } }
//定义交通工具子类 package project1; public class jtgjzilei extends jiaotonggongju { public jtgjzilei() { super(); } public jtgjzilei(String leixing,String chengyunshang,String num) { super(leixing,chengyunshang,num); } public void gongju() { System.out.println("正在运输中......"); } }
//定义快递属性类和抽象方法 package project1; import javax.crypto.interfaces.DHPublicKey; public class kuaidi { double weight; String ID; String place; public kuaidi(){ } public kuaidi(double weight,String ID,String place) { super(); this.weight=weight; this.ID=ID; this.place=place; } //运送前 public void before() { System.out.println("订单开始处理"); System.out.println("快递单号:"+this.ID); System.out.println("货物重量:"+this.weight+"kg"); System.out.println(this.place+"仓库接货"); System.out.println("仓库拣货"); System.out.println("拣货完毕"); System.out.println("已到达配送站,随机分配运货人"); System.out.println("快件准备派送......"); } //运输工具(交通工具子类) jtgjzilei tool=new jtgjzilei("汽车","顺丰快递","0328"); //运送中 public void ing() { System.out.println("承运商:"+tool.getChengyunshang()+"n"+"编号:"+tool.getNum()+"n"+"运送工具:"+ tool.getLeixing()); tool.gongju(); } //运送后 public void later() { System.out.println("快件已签收"); System.out.println("承运商"+tool.getChengyunshang()+"派送完毕"); } }
//测试类 package project1; import java.util.Scanner; public class Test { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); kuaidi express=new kuaidi(); System.out.println("正在创建快递项目"); System.out.println("请输入快递重量:"); express.weight=scanner.nextDouble(); System.out.println("请输入快递单号:"); express.ID=scanner.next(); System.out.println("请输入发货地点:"); express.place=scanner.next(); //调用运送前 System.out.println("n"); express.before(); System.out.println("n"); //调用运送中 express.ing(); System.out.println("n"); //调用运送后 express.later(); System.out.println("n"); } }测试
