**分析图片信息，可以看出我们需要创建一个菜单类，查看餐带类和点赞菜单类**

**1.首先我们创建一个菜单类，用来定义菜单的属性，使用到封装，构造方法，和toString方法。**

public class Food {
        //菜单
     
     @Override
     public String toString() {
        
     return "Food{" +
     "num=" + num +
     ", name='" + name + '\'' +
     ", price=" + price +
     '}';
     }
     
     private int num;
     private String name;
     private double price;
     
     public Food() {
        
     }
     
     public Food(int num, String name, double price) {
        
     this.num = num;
     this.name = name;
     this.price = price;
     }
     
     public int getNum() {
        
     return num;
     }
     
     public void setNum(int num) {
        
     this.num = num;
     }
     
     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;
     }
    }

**2.其次，我们在创建一个查看餐袋类**

public class SeeFood {
        //查看餐带
     private int num;//序号
     private String name;//订餐人
     //private String information;//信息
     private String food;//菜品
     private int num1;//份数
     private int date;//送餐日期
     private String address;//送餐地址
     private double money;//金额
     private String state;//订单状态
     
     @Override
     public String toString() {
        
     return "SeeFood{" +
     "num=" + num +
     ", name='" + name + '\'' +
     ", food='" + food + '\'' +
     ", num1=" + num1 +
     ", date='" + date + '\'' +
     ", address='" + address + '\'' +
     ", money=" + money +
     ", state='" + state + '\'' +
     '}';
     }
     
     public int getNum() {
        
     return num;
     }
     
     public void setNum(int num) {
        
     this.num = num;
     }
     
     public String getName() {
        
     return name;
     }
     
     public void setName(String name) {
        
     this.name = name;
     }
     
     public String getFood() {
        
     return food;
     }
     
     public void setFood(String food) {
        
     this.food = food;
     }
     
     public int getNum1() {
        
     return num1;
     }
     
     public void setNum1(int num1) {
        
     this.num1 = num1;
     }
     
     public int getDate() {
        
     return date;
     }
     
     public void setDate(int date) {
        
     this.date = date;
     }
     
     public String getAddress() {
        
     return address;
     }
     
     public void setAddress(String address) {
        
     this.address = address;
     }
     
     public double getMoney() {
        
     return money;
     }
     
     public void setMoney(double money) {
        
     this.money = money;
     }
     
     public String getState() {
        
     return state;
     }
     
     public void setState(String state) {
        
     this.state = state;
     }
     
     public SeeFood() {
        
     }
     
     public SeeFood(int num, String name, String food,
     int num1, int date, String address,
     double money, String state) {
        
     this.num = num;
     this.name = name;
     this.food = food;
     this.num1 = num1;
     this.date = date;
     this.address = address;
     this.money = money;
     this.state = state;
     }
    }

**3.再创建一个点赞菜单类**

public class FabulousFood {
        //点赞菜单
     private int num;//序号
     private String name;
     private double price;
     private int numfabulous;//点赞序号
     private String fabulous;
     
     @Override
     public String toString() {
        
     return "FabulousFood{" +
     "num=" + num +
     ", name='" + name + '\'' +
     ", price=" + price +" "+
     numfabulous +
     fabulous + '\'' +
     '}';
     }
     
     public FabulousFood() {
        
     }
     
     public FabulousFood(int num, String name, double price, int numfabulous, String fabulous) {
        
     this.num = num;
     this.name = name;
     this.price = price;
     this.numfabulous = numfabulous;
     this.fabulous = fabulous;
     }
     
     public int getNum() {
        
     return num;
     }
     
     public void setNum(int num) {
        
     this.num = num;
     }
     
     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 int getNumfabulous() {
        
     return numfabulous;
     }
     
     public void setNumfabulous(int numfabulous) {
        
     this.numfabulous = numfabulous;
     }
     
     public String getFabulous() {
        
     return fabulous;
     }
     
     public void setFabulous(String fabulous) {
        
     this.fabulous = fabulous;
     }
    }

**4.创建点餐系统实现其功能，每个功能都使用方法来实现**

import java.util.ArrayList;
    import java.util.Iterator;
    import java.util.Scanner;
     
    public class OrderFood {
        //点餐
     static Scanner sc=new Scanner(System.in);
     static int date;//送餐时间
     static int number=0;//餐带序号
     public static void main(String[] args) {
        
     ArrayList<Food> list = new ArrayList<>();
     list.add(new Food(1, "红烧茄子", 24));
     list.add(new Food(2, "红烧排骨", 36));
     list.add(new Food(3, "鱼香肉丝", 32));
     ArrayList<FabulousFood> list2 = new ArrayList<>();
     list2.add(new FabulousFood(1, "红烧茄子", 24,0,"赞"));

     System.out.println("2、查看餐带");
     System.out.println("3、签收订单");
     System.out.println("4、删除订单");
     System.out.println("5、我要点赞");
     System.out.println("6、退出系统");
     System.out.println("*******************************");
     System.out.println("请选择：");
     String num=sc.next();
     if (num.equals("1")){
