java实现飞机选票

通过输入票价、月份来输出价格。

代码如下

 public static void main(String[] args) {Scanner mm = new Scanner(System.in);System.out.println("请输入票价；");Double money = mm.nextDouble();System.out.println("请输入月份；");int month = mm.nextInt();System.out.println("请输入仓位；");String type = mm.next();System.out.println(cale(money,month,type));}
//cale方法public static Double cale(Double money, int month, String type) {if (month >=5&& month <= 10) {switch (type) {case "头等舱":money *= 0.9;break;case "经济舱":money *= 0.85;break;}} else if (month == 11 || month == 12 || month >= 4 && month <= 7) {switch (type) {case "头等舱":money *= 0.7;break;case "经济舱":money *= 0.65;break; }} else {System.out.println("你输入的月份有误");}return money;}

输入票价、月份、仓位 效果如图
