java实现外卖订餐系统

java实现外卖订餐系统

本文实例为大家分享了java实现外卖订餐系统的具体代码，供大家参考，具体内容如下

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

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 fabtlcYqulous;

@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

ArrayList 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"));
