**5.退出**  
![20210331153804931.png][]  
**首先我们分析图片里的内容，需要创建一个货物类。**

public class Goods {
        
      private String number;
      private double price;
      private String name;
     
      @Override
      public String toString() {
        
        return "Goods{" +
            "number='" + number + '\'' +
            ", price=" + price +
            ", name='" + name + '\'' +
            '}';
      }
     
      public String getNumber() {
        
        return number;
      }
     
      public void setNumber(String number) {
        
        this.number = number;
      }
     
      public double getPrice() {
        
        return price;
      }
     
      public void setPrice(double price) {
        
        this.price = price;
      }
     
      public String getName() {
        
        return name;
      }
     
      public void setName(String name) {
        
        this.name = name;
      }
     
      public Goods() {
        
      }
     
      public Goods(String number, double price, String name) {
        
        this.number = number;
        this.price = price;
        this.name = name;
      }
    }

**这里我们把每一个功能写进一个类里面，以便更好的观察。**  
**1.创建一个货物清单类**

import java.util.ArrayList;
    import java.util.Iterator;
     
    public class CargoList {
        //货物清单
      public void cargoList(ArrayList<Goods> list){
        
        System.out.println("============货物清单============");
        Iterator<Goods> it = list.iterator();
        while (it.hasNext()){
        
          System.out.println(it.next());
        }
      }
    }

**2.创建一个增加货物类**

import java.util.ArrayList;
    import java.util.Scanner;
     
    public class IncreaseCargo {
        //增加货物
      static Scanner sc=new Scanner(System.in);
      public void add(ArrayList list){
        
        System.out.println("选择的是商品添加功能");
        System.out.println("输出商品编号ID");
        String num=sc.next();
        System.out.println("输入商品单价");
        double price=sc.nextDouble();
        System.out.println("输入商品名称");
        String name=sc.next();
        Goods g1 = new Goods(num, price, name);
        list.add(g1);
        System.out.println("添加成功");
      }
    }

**3.创建一个删除货物类**

import java.util.ArrayList;
    import java.util.Scanner;
     
    public class DeleteGoods {
        //删除商品
      static Scanner sc=new Scanner(System.in);
      public void delete(ArrayList<Goods> list){
        
        System.out.println("选择的是删除功能");
        System.out.println("输入要删除的商品编号ID");
        String num=sc.next();
        for (int i = 0; i <list.size() ; i++) {
        
          if (list.get(i).getNumber().equals(num)){
        
            list.remove(list.get(i));
          }
        }
        System.out.println("删除成功");
     
      }
    }

**4.创建一个修改货物类**

import java.util.ArrayList;
    import java.util.Iterator;
    import java.util.Scanner;
     
    public class ModificationOfGoods {
        //修改货物
      static Scanner sc=new Scanner(System.in);
      public void modify(ArrayList<Goods> list){
        
        System.out.println("选的是修改功能");
        System.out.println("输入你要修改的商品编号ID");
        String num=sc.next();
        System.out.println("输入新的商品编号");
        String num1=sc.next();
        System.out.println("输入商品单价");
        double price=sc.nextDouble();
        System.out.println("输入商品名称");
        String name=sc.next();
        for (int i = 0; i <list.size() ; i++) {
        
          if (num.equals(list.get(i).getNumber())){
        
            list.set(i,new Goods(num1,price,name));
          }
        }
        System.out.println("修改成功");
     
     
      }
    }

**5.创建一个超市管理系统实现其功能**

import java.util.ArrayList;
    import java.util.Scanner;
     
     
    public class SuperMarket {
        
      static Scanner sc = new Scanner(System.in);
      public static void main(String[] args) {
        
        ArrayList<Goods> list = new ArrayList<>();
        list.add(new Goods("1000",10,"笔记本"));
        list.add(new Goods("1001",2,"西红柿"));
        list.add(new Goods("1002",5,"辣条"));
        //list.get(1).setName("hhhhhh");
        //System.out.println(list.get(1).getName());
        System.out.println("============超市管理系统============");
        while (true){
        
          System.out.println("1:货物清单 2:增加货物 3:删除货物 4:修改货物 5:退出");
          System.out.println("请输入你要操作的编号：");
          String num=sc.next();
          if (num.equals("1")){
        
            CargoList cl = new CargoList();
            cl.cargoList(list);
          }else if (num.equals("2")){
        
            IncreaseCargo ic = new IncreaseCargo();
            ic.add(list);
          }else if (num.equals("3")){
        
            DeleteGoods dg = new DeleteGoods();
            dg.delete(list);
          }else if (num.equals("4")){
        
            ModificationOfGoods mog = new ModificationOfGoods();
            mog.modify(list);
          }else if (num.equals("5")){
        
            System.out.println("欢迎下次光临");
            break;
          }else {
        
            System.err.println("输入错误，请重新输入！");
          }
          System.out.println();
          System.out.println();
        }
      }
    }
