java - 计算小时加一

Question

学习 Java 我当前的问题是下面的“else”语句。如果我输入 3 小时 55 分钟，我要查找的结果是:“五比四”

使用下面的代码我得到: 请输入营业时间(1 点到 12 点之间): 3 请输入分钟(1 到 60 之间): 55 五比三

有人可以告诉我我做错了什么吗？ (谢谢)

// actual calcuations

    if(minuteValue==0){
        result = hourPart + minutePart + " o'clock"; // eg two o'clock (the String o'clock defined later in the minute values)
    }
    else if (minuteValue <= 30 ){
        result = minutePart + " past " + hourPart; // eg ten past five
    }
    else
    {
       int remainingtime = 60 - minuteValue;
       int nexthr = hourValue + 1;
       if(nexthr==13) nexthr = 1;  

       result = getHourString(remainingtime) + " to " + hourPart; // eg twenty to five

    }

    return result;

Answer 1

首先，您没有使用nexthr:

result = getHourString(remainingtime) + " to " + hourPart; //where's nexthr?

其次，这里发生了很多事情。只需使用 hourValue 和 minuteValue 来跟踪输入的时间。将 minutePart 更改为 monthValue，将 hourPart 更改为 hourValue 即可完成:

String result;
int minuteValue = 55;
int hourValue = 9;

if(minuteValue==0){
    result = hourValue + minuteValue + " o'clock"; // eg two o'clock (the String o'clock defined later in the minute values)
}
else if (minuteValue <= 30 ){
    result = minuteValue + " past " + hourValue; // eg ten past five
}
else
{
   int remainingtime = 60 - minuteValue;
   int nexthr = hourValue + 1;
   if(nexthr==13) nexthr = 1;  
   result = remainingtime + " to " + nexthr; // eg twenty to five

}

System.out.println(result);

结果:5 到 10
