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 number=0;//餐带序号

 ArrayList<FabulousFood> list2 = new ArrayList<>();
 list2.add(new FabulousFood(1, "红烧茄子", 24,0,"赞"));
 list2.add(new FabulousFood(2, "红烧排骨", 36,0,"赞"));
 list2.add(new FabulousFood(3, "鱼香肉丝", 32,0,"赞"));
