菜品上架与展示

1、功能简介

1、实现菜品的上架
2、实现菜品的展示

2、代码展示

2.1 food类

package com.ham.pkg.ArryList;public class Food {private String name;private double price;private String desc;public Food(String name, double price, String desc) {this.name = name;this.price = price;this.desc = desc;}//无参构造器public Food() {}public String getName() {return name;}public void setName(String name) {this.name = name;}public double getPrice() {return price;}public void setPrice(double price) {this.price = price;}public String getDesc() {return desc;}public void setDesc(String desc) {this.desc = desc;}
}

2.1 foodOpertor类

package com.ham.pkg.ArryList;import java.util.ArrayList;
import java.util.Scanner;public class FoodOpertor {//菜品操作类//定义一个ArryList存储菜品信息ArrayList<Food> foods=new ArrayList<>();//添加菜品public void addfood(){Food f=new Food(); //创建菜品类Scanner sc =new Scanner(System.in);System.out.println("输入菜品名称");String name=sc.next();f.setName(name);System.out.println("输入菜品价格");Double price=sc.nextDouble();f.setPrice(price);System.out.println("输入菜品描述");String desc=sc.next();f.setDesc(desc);foods.add(f); //将数据添加到list中去System.out.println("上架成功");}//浏览菜品public  void  LookFood(){if (foods.size()==0){return;}for (int i=0;i<foods.size();i++){Food f=foods.get(i);System.out.println(f.getName());System.out.println(f.getPrice());System.out.println(f.getDesc());}}//负责展示菜名public void  start(){while (true) {System.out.println("请选择功能");System.out.println("1.上架菜品");System.out.println("2.展示菜品");System.out.println("3.退出");Scanner sc=new Scanner(System.in);System.out.println("请选择");String index =sc.next();switch (index){case "1":addfood();break;case "2":LookFood();break;case "3":return;default:System.out.println("输入不合法");}}}}

2.1 foodCase类

package com.ham.pkg.ArryList;public class ArryListCase1 {public static void main(String[] args) {FoodOpertor opertor =new FoodOpertor();opertor.start();}
}
