java面试题：酒店预订！

public static void main(String[] args) {

Scanner input = new Scanner(System.in)

System.out.println("是否是会员？y/n")

String H = input.next()

System.out.println("请输入入住日期：")

System.out.println("例如2009-03-16")

String in = input.next()

System.out.println("请输离开日期：")

System.out.println("例租腔如2009-03-16")

String out = input.next()

//String in = s.substring(5,15)

//String out = s.substring(15,26)

//System.out.println(in+" "+out)

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd")

Calendar c1 = Calendar.getInstance()

Calendar c2 = Calendar.getInstance()

try {

c1.setTime(sdf.parse(in))

} catch (ParseException e) {

// TODO Auto-generated catch block

e.printStackTrace()

}

long time1 = c1.getTimeInMillis()

long time2 = c2.getTimeInMillis()

long tian = (time2-time1)/(1000*24*3600)

long tian1 = tian

System.out.println("tian"+tian)

int week1 = c1.get(Calendar.DAY_OF_WEEK)-1

//System.out.println(week1)

//弊罩衫int week2 = c2.get(Calendar.DAY_OF_WEEK)-1

//System.out.println(week2)

int count = 0

while(tian1>0){

if(week1 == 6 || week1==0){

count++

}

if(week1==6){

week1 = 0

week1--

}

tian1--

week1++

}

System.out.println("count "+count)

long rujia

long qitian

long hanting

if(H.equals("y")){

rujia = (tian-count)*80+count*80

System.out.println("tian "+tian)

qitian = (tian-count)*110+count*50

hanting = (tian-count)*100+count*40

}else{

qitian = (tian-count)*160+count*60

hanting = (tian-count)*220+count*150

}

System.out.println("tian "闷带 + tian)

System.out.println("rujia"+rujia)

System.out.println("hanting"+hanting)

System.out.println("qitian"+qitian)

if(rujia<qitian &&rujia<hanting){

System.out.println("如家")

}else if(qitian<rujia &&qitian<hanting){

System.out.println("七天")

}else if(hanting<rujia &&hanting<qitian){

System.out.println("汉庭")

}else if(hanting==rujia || hanting==qitian){

System.out.println("汉庭")

}else if(qitian==rujia &&qitian<hanting){

System.out.println("七天")

}

}

我没怎么测试 自己测测吧 还有一些约束用户输入啥的 严谨性什么的

1、艺龙酒店预订

2、携程酒店机票雹燃型火车票

3、去哪儿酒店预段迹定

4、朋友家精选民俗源猜

5、同程旅游

这些都可以预定的，去哪儿 携程 同城都还可以，还可以新人领取优惠券抵用，反正我就是用的这三个比较多。望采纳，祝你生活愉快。
