package test;
import java.util.Calendar;
import java.util.Scanner;
//机票购买
public class Case1 {
public static void main(String[] args) {
// Calendar c = Calendar.getInstance(); //调用当前月份
// int month =(c.get(Calendar.MONTH)+1);
// System.out.println(month);
double price = 880.00;
// double a = count();
// System.out.println(a);
price(price);
}
public static double count(){
Scanner sc = new Scanner(System.in);
System.out.println("请输入您要选择的座位（头等舱：1；经济舱：2）：");
int choice = sc.nextInt();
Calendar c = Calendar.getInstance(); //调用当前月份
int month =(c.get(Calendar.MONTH)+1);
