使用 jodatime 查找剩余日期和时间

发布于 2024-12-14 02:33:30 字数 764 浏览 0 评论 0原文

我想使用 joda 时间进行比较（查找剩余天数和两天之间的时间）。我正在使用两个像这样的 DateTime 对象（一个正在开始，另一个正在结束）

DateTime endDate  = new DateTime(2011,12,25,0,0,0,0);   
DateTime strtDate = new DateTime();

现在我有兴趣找到像这样的剩余日期和时间 天：49小时：5分钟：52秒：45（这里不考虑年和月..）

现在我继续像这样的周期类

Period period = new Period();

PeriodFormatter formatter = new PeriodFormatterBuilder()
    .appendSeconds()
    .appendMinutes()
    .appendHours()
    .appendDays()
    .appendMonths()
    .appendYears()
    .printZeroNever()
    .toFormatter();

现在我得到的结果是年，月，日， ETC... 在这种情况下，我总是会得到 1-30 之间的天数（而不是 31,45,49...（我想要的））。

那么我怎样才能得到这个东西（有没有我缺少的方法）或者我需要以编程方式处理这个问题，因为我读到 joda 时间非常灵活，所以我非常确定会有这样的方法。

如果您熟悉，请分享您的知识。

I want to compare(finding remaining days and time between two days) using joda time.
I am taking two DateTime object like this(one is starting and another is ending)

DateTime endDate  = new DateTime(2011,12,25,0,0,0,0);   
DateTime strtDate = new DateTime();

Now i am interested to find remaining date and time like this
days:49 Hrs:5 Min:52 Sec:45(Not considering Year and month here..)

Now I go ahead with period class like this

Period period = new Period();

PeriodFormatter formatter = new PeriodFormatterBuilder()
    .appendSeconds()
    .appendMinutes()
    .appendHours()
    .appendDays()
    .appendMonths()
    .appendYears()
    .printZeroNever()
    .toFormatter();

Now in result what i get year,month,Day,etc...
in this case i will get days between 1-30(not 31,45,49...(which I want)) always.

So how can i get this thing(is there any method that I am missing) or I need to handle this programmatically, as I read that joda time is very flexible so I am very sure that there will be any method like this.

If you are familiar then kindly share your knowledge.

使用 PeriodType.dayTime 定义从天开始的所有标准字段()。

例如：

DateTime startDate = DateTime.now(); // now() : since Joda Time 2.0
DateTime endDate = new DateTime(2011, 12, 25, 0, 0);

Period period = new Period(startDate, endDate, PeriodType.dayTime());

PeriodFormatter formatter = new PeriodFormatterBuilder()
        .appendDays().appendSuffix(" day ", " days ")
        .appendHours().appendSuffix(" hour ", " hours ")
        .appendMinutes().appendSuffix(" minute ", " minutes ")
        .appendSeconds().appendSuffix(" second ", " seconds ")
        .toFormatter();

System.out.println(formatter.print(period));

示例输出

startDate 和 endDate 之间的周期为

47天12小时46分47秒

或

PeriodFormatter formatter = new PeriodFormatterBuilder()
        .appendPrefix("Day:", " Days:").appendDays()
        .appendPrefix(" Hour:", " Hours:").appendHours()
        .appendPrefix(" Minute:", " Minutes:").appendMinutes()
        .appendPrefix(" Second:", " Seconds:").appendSeconds()
        .toFormatter();

有输出

天：47 小时：12 分钟：46 秒：47

Defines all standard fields from days downwards with PeriodType.dayTime().

For example :

DateTime startDate = DateTime.now(); // now() : since Joda Time 2.0
DateTime endDate = new DateTime(2011, 12, 25, 0, 0);

Period period = new Period(startDate, endDate, PeriodType.dayTime());

PeriodFormatter formatter = new PeriodFormatterBuilder()
        .appendDays().appendSuffix(" day ", " days ")
        .appendHours().appendSuffix(" hour ", " hours ")
        .appendMinutes().appendSuffix(" minute ", " minutes ")
        .appendSeconds().appendSuffix(" second ", " seconds ")
        .toFormatter();

System.out.println(formatter.print(period));

Sample output

Period between startDate and endDate is

47 days 12 hours 46 minutes 47 seconds

PeriodFormatter formatter = new PeriodFormatterBuilder()
        .appendPrefix("Day:", " Days:").appendDays()
        .appendPrefix(" Hour:", " Hours:").appendHours()
        .appendPrefix(" Minute:", " Minutes:").appendMinutes()
        .appendPrefix(" Second:", " Seconds:").appendSeconds()
        .toFormatter();

with output

Days:47 Hours:12 Minutes:46 Seconds:47

如果您希望以更漂亮的格式输出，那么您也可以使用此代码片段

val startDate = DateTime.now()
val endDate = DateTime(endTime)
val period = Period(startDate, endDate)

val periodFormatter = PeriodFormatterBuilder().apply {
    when {
        period.days > 0 -> appendDays().appendSuffix(" day", " days")
        period.hours > 0 -> appendHours().appendSuffix(" hour", " hours")
        period.minutes > 0 -> appendMinutes().appendSuffix(" minute", " minutes")
    }
}.toFormatter()

periodFormatter.print(period)

If you want the output in prettier format then you can use this snippet too

val startDate = DateTime.now()
val endDate = DateTime(endTime)
val period = Period(startDate, endDate)

val periodFormatter = PeriodFormatterBuilder().apply {
    when {
        period.days > 0 -> appendDays().appendSuffix(" day", " days")
        period.hours > 0 -> appendHours().appendSuffix(" hour", " hours")
        period.minutes > 0 -> appendMinutes().appendSuffix(" minute", " minutes")
    }
}.toFormatter()

periodFormatter.print(period)
