课后作业机票，赌骰子游戏，switch的使用实例

一，课后第三题机票

package com.bd22;

import java.util.Scanner;

public class AirTicket {

    public static void main(String[] args) {

        System.out.println("请输入您出行的月份");

        Scanner sc = new Scanner(System.in);

        int month = sc.nextInt();//输入月份

        System.out.println("请问您选择头等舱还是经济舱？头等舱输入1，经济舱输入2");

        int air = sc.nextInt();//输入仓位

        double money = ;//设定机票

        double pay = ;//赋值

        if(month>=&&month<=) {

            if(air==) {

                pay = money*0.9;

                System.out.println("您的机票价格为："+pay);

            }else {

                pay = money*0.6;

                System.out.println("您的机票价格为："+pay);

            }

        }else {

            if(air==) {

                pay = money*0.5;

                System.out.println("您的机票价格为："+pay);

            }else {

                pay = money*0.4;

                System.out.println("您的机票价格为："+pay);

            }

        }

    }

}

二，赌骰子游戏

import java.util.MissingFormatArgumentException;

import java.util.Scanner;

public class Game {

    public static void main(String[] args) {

        System.out.println("欢迎来到澳门大赌场");

        int money = ;

        System.out.println("是否开始Game(是/否)?");

        Scanner sc = new Scanner(System.in);

        String choose = sc.next();

        if(!"否".equals(choose)) {

            int a = (int)(Math.random()*);

            String result =(a)>=?"大":"小";

            System.out.println("请下注");

            int pay = sc.nextInt();

            System.out.println("请压大或者压小:");

            String guess = sc.next();

            System.out.println("买定离手"+a);

            if(guess.equals(result)) {

                System.out.println("恭喜你压中了");

                money += pay;

                System.out.println("您获得"+money+"金钱");

            }else {

                System.out.println("对不起，您没有压中");

                money -= pay;

                System.out.println("您的余额为："+money);

            }

        }else {

            System.out.println("你走吧，穷逼");

        }

    }

}

三，switch实现135学习，246复习，周日休息

package com.bd22;

import java.util.Scanner;

public class Swish {

    public static void main(String[] args) {

        //判断135学习，246复习，7休息

        Scanner sc = new Scanner(System.in);

        System.out.println("请问查询星期？");

        int week = sc.nextInt();

        switch (week) {

        case :

        case :

        case :

            System.out.println("学习");

            break;

        case :

        case :

        case :

            System.out.println("复习");

            break;

        default:

            System.out.println("休息");

        }

    }

}
