外卖点单系统java课程设计 点餐外卖系统开发

一、使用技术

javaSE

二、实现功能

外卖订餐系统

具体要求如下：

使用选择结构，循环结构，数组的知识实现一个外卖订餐系统

三、运行效果图如下：

1.订餐功能

2.查看餐袋

3.签收订单

4.删除订单

5.点赞

6.退出

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"));
        list2.add(new FabulousFood(2, "红烧排骨", 36,0,"赞"));
        list2.add(new FabulousFood(3, "鱼香肉丝", 32,0,"赞"));
        ArrayList<SeeFood> list1 = new ArrayList<>();
        System.out.println("      欢迎使用“外卖点餐系统”");
        System.out.println("*******************************");
        orderFood(list,list1,list2);
    }

    public static void orderFood(ArrayList<Food> list1,ArrayList<SeeFood> list2,ArrayList<FabulousFood> list3){//点餐系统界面
        // System.out.println("      欢迎使用“外卖点餐系统”");
        //System.out.println("*******************************");
        System.out.println("1、我要点餐");
        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")){
                orderingFood(list1,list2,list3);
        }else if (num.equals("2")){
            seeFood(list1, list2,list3);
        }else if (num.equals("3")){
            signFor(list1, list2,list3);

        }else if (num.equals("6")){
            System.out.println("谢谢使用，欢迎下次光临！");
            return;
        }else {
            System.out.println("输出错误，请重新输入！");
            orderFood(list1,list2,list3);
        }
    }

    public static void fabulousFood(ArrayList<Food> list,ArrayList<SeeFood> list2,ArrayList<FabulousFood> list3){//点赞
        System.out.println("******我要点赞******");
        System.out.println("序号   菜名   单价");
        Iterator<FabulousFood> it = list3.iterator();
        while (it.hasNext()){

        System.out.println("点赞成功！");
        System.out.println("输入0返回");
        int b=sc.nextInt();
