外卖订餐系统的实现
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”");
