更新時(shí)間：2021年01月20日 08:54:24 作者：小蘇(º﹃º )

這篇文章主要為大家詳細(xì)介紹了java實(shí)現(xiàn)外賣訂餐系統(tǒng)，文中示例代碼介紹的非常詳細(xì)，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

本文實(shí)例為大家分享了java實(shí)現(xiàn)外賣訂餐系統(tǒng)的具體代碼，供大家參考，具體內(nèi)容如下

一、使用技術(shù)

javaSE

二、實(shí)現(xiàn)功能

外賣訂餐系統(tǒng)

具體要求如下：

使用選擇結(jié)構(gòu)，循環(huán)結(jié)構(gòu)，數(shù)組的知識實(shí)現(xiàn)一個(gè)外賣訂餐系統(tǒng)

三、運(yùn)行效果圖

1.訂餐功能

2.查看餐袋

3.簽收訂單

4.刪除訂單

5.點(diǎn)贊

6.退出

分析圖片信息，可以看出我們需要?jiǎng)?chuàng)建一個(gè)菜單類，查看餐帶類和點(diǎn)贊菜單類

1.首先我們創(chuàng)建一個(gè)菜單類，用來定義菜單的屬性，使用到封裝，構(gòu)造方法，和toString方法。

public class Food {//菜單

 @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，我們在創(chuàng)建一個(gè)查看餐袋類

public class SeeFood {//查看餐帶
 private int num;//序號
 private String name;//訂餐人
 //private String information;//信息
 private String food;//菜品
 private int num1;//份數(shù)
 private int date;//送餐日期
 private String address;//送餐地址
 private double money;//金額
 private String state;//訂單狀態(tài)

 @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.再創(chuàng)建一個(gè)點(diǎn)贊菜單類

public class FabulousFood {//點(diǎn)贊菜單
 private int num;//序號
 private String name;
 private double price;
 private int numfabulous;//點(diǎn)贊序號
 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.創(chuàng)建點(diǎn)餐系統(tǒng)實(shí)現(xiàn)其功能，每個(gè)功能都使用方法來實(shí)現(xiàn)
