java - 如何创建时间数组

Question

我有一个数组列表 arr，其中包含一系列数字，例如 07, 52, 25, 10, 19, 55, 15, 18, 41。在此列表中，第一项是小时，第二项是分钟，第三项是第二项，比如 07:52:25。现在我想创建一个时间数组，在其中插入这些值并进行一些算术运算，例如第一个索引和第二个索引之间的差，这给了我时间差。那么我该怎么做呢？

ArrayList arr = new ArrayList();
StringTokenizer st = new StringTokenizer(line, ":Mode set - Out of Service In Service");
while(st.hasMoreTokens()){
    arr.add(st.nextToken());
}

好吧，我想我明白你想要你的代码做什么。这是我的做法。

public class DateHandler
{
    public DateHandler(int seconds, int minutes, int hours)
    {
        this.seconds = seconds;
        this.minutes = minutes;
        this.hours = hours;
    }

    public String toString()
    {
        return "Seconds: "+seconds+" Minutes: "+minutes+" Hours: "+hours;
    }

    public int seconds;
    public int minutes;
    public int hours;
}

public class Main
{
    public static void main(String args[])
    {
        int[] data = {07, 52, 25, 10, 19, 55, 15, 18, 41}
        int numberOfDates = data.length/3//Divide by 3 because there are 3 numbers per date
        ArrayList<DateHandler> dates = new ArrayList<DateHandler>(numberOfDates);
        for(int x=0;x<numberOfDates;x++)
        {
            int index = x*3;
            DateHandler date = new DateHandler(data[index],data[index+1],data[index+2]);
            System.out.println("added date: "+date.toString());
            dates.add(date);
        }

        //here you can do your calculations.
    }
}

我希望这有帮助!
