java-点菜系统

java基础程序-点菜系统

基础思路

1.点菜系统需要一个类(目前没有考虑用户类，水平不够，日后再来补坑)即Dish类,Dish类下有id,name,price。

    private int id;
    private String name;
    private double price;

对Dish进行构造

    public Dish(int id, String name, double price) {
        this.id = id;
        this.name = name;
        this.price = price;
    }

对Dish进行Getter和Setter

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    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;
    }

重写toString

    public String toString() {
        return "Dish{" +
                "id=" + id +
                ", name='" + name + '\'' +
                ", price=" + price +
                '}';
    }

2.对点餐系统进行编写
ShowOrder 显示界面

    public static void ShowOrder(){
        System.out.println("---欢迎您来点菜---");
        System.out.println("请输入数字进行点菜");
        System.out.println("显示全部菜\t\t1");
        System.out.println("点菜\t\t\t\t2");
        System.out.println("删菜\t\t\t\t3");
        System.out.println("结账\t\t\t\t4");
    }

InitDish 对主菜单进行初始化

    public static void InitDish(){
        dishList.add(new Dish(1,"香辣肉丝",29.0));
        dishList.add(new Dish(2,"炖王八",90.0));
        dishList.add(new Dish(3,"炒蔬菜",15.0));
    }

ShowMenu 显示主菜单

    public static void ShowMenu(){
        for (int i = 0; i < dishList.size(); i++) {
            System.out.println(dishList.get(i));
        }
    }

ShowPersonMenu 显示自己已经点过的菜单

    public static void ShowPersonMenu(){
        for (int i = 0; i < PersonList.size(); i++) {
            System.out.println(PersonList.get(i));
        }
    }

OrderDish 进行点菜

    public static void OrderDish(){
        System.out.println("请输入您点菜的序号");
        int id=sc.nextInt();
        PersonList.add(dishList.get(id-1));
    }

DelectDish 删除菜单

    public static void DelectDish(){
        System.out.println("输入您要删除的序号");
        int id=sc.nextInt();
        PersonList.remove(id-1);
    }

BuyOrder 结账

    public static void BuyOrder(){
        double money=0.0;
        for (int i = 0; i < PersonList.size(); i++) {
            money=money+PersonList.get(i).getPrice();
        }
        System.out.println("您总共消费"+money);
    }
