如何找到两个日期之间的差异持续时间 [英] How to find the duration of difference between two dates

问题描述

我有两个约会，例如。 1989-3-21、2016-3-21，我想找出两个日期之间的差值持续时间。为此，我正在尝试以下代码，但无法获得日期差的持续时间。

I have two dates, eg. 1989-3-21, 2016-3-21 and I want to find the duration of difference between those dates. For this I am trying the following code but I am unable to get the duration of difference in dates.

public String getTimeDiff(Date dateOne, Date dateTwo) {
        String diff = "";
        long timeDiff = Math.abs(dateOne.getTime() - dateTwo.getTime());
        diff = String.format("%d hour(s) %d min(s)", TimeUnit.MILLISECONDS.toHours(timeDiff),
                TimeUnit.MILLISECONDS.toMinutes(timeDiff) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(timeDiff)));
        return diff;
}

推荐答案

像以前一样初始化日期调用公用字符串getTimeDiff（Date dateOne，Date dateTwo）：

Initialize your dates like so before calling public String getTimeDiff(Date dateOne, Date dateTwo):

    Date dateOne=null,dateTwo=null;
    try {
        dateOne = new SimpleDateFormat( "yyyy-MM-dd" ).parse("2016-3-21");
        dateTwo =  new SimpleDateFormat( "yyyy-MM-dd" ).parse("1989-3-21");
    } 
    catch (ParseException ex) {     
    }
    System.out.println( getTimeDiff(dateOne,dateTwo));



    public String getTimeDiff(Date dateOne, Date dateTwo) {
        String diff = "";
        long timeDiff = Math.abs(dateOne.getTime() - dateTwo.getTime());
        diff = String.format("%d date(s) ", TimeUnit.MILLISECONDS.toDays(timeDiff));
        return diff;
    }

由于您的日期不是默认格式，因此您必须使用SimpleDateFormat显式声明日期的格式。

Since your Dates aren't in their default format you will have to use a SimpleDateFormat to explicitly declare the format of your Dates.
