Java项目案例

机票价格按照淡季旺季、头等舱和经济舱收费、输入机票原价、月份和头等舱或经济舱。机票最终优惠价格的计算方案如下：旺季（5-10月）头等舱9折，经济舱8.5折，淡季（11月到来年4月）头等舱7折，经济舱6.5折。

import java.util.Scanner;

public class AirTickets {
   public static void main(String[] args) {
	   Scanner sc = new Scanner(System.in);
	   System.out.println("请输入机票原价：");
	   double money = sc.nextDouble();
	   
	   System.out.println("请输入机票月份（1-12）：");
	   int month = sc.nextInt();
	   
	   System.out.println("请选择仓位类型：");
	   String type = sc.next();
	   
	   System.out.println("机票优惠后的价格为：" + result(money,month,type));
   }
   
   public static double result(double money , int month, String type) {
