Convert seconds to years/days/hours/minutes automatically, using JodaTime?

Question

Is there way to convert 'x' seconds to y hours and z seconds when say x exceeds 3600 seconds? Similarly, convert it to 'a minutes and b seconds' when x exceeds 60 but is less than 3600 seconds, using JodaTime? I understand that I would have to specify what I need in the PeriodFormatter, but I don't want to specify it - I want a formatted text based on value of seconds.

This is similar to how you would post on a forum and then your post will initially be shown as 'posted 10 seconds ago'.. after 1 minute you would see 'posted 1minute 20 seconds ago' and likewise for weeks,days,years.

I'm not sure why you don't want to specify what you need in PeriodFormatter. JodaTime doesn't know how you want to display a period as a string, so you need to tell it via the PeriodFormatter.

As 3600 seconds is 1 hour, using the formatter properly will automatically do this for you. Here's a code example using a number of different inputs on the same formatter which should achieve your desired result.

    Seconds s1 = Seconds.seconds(3601);
    Seconds s2 = Seconds.seconds(2000);
    Seconds s3 = Seconds.seconds(898298);
    Period p1 = new Period(s1);
    Period p2 = new Period(s2);
    Period p3 = new Period(s3);

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

    System.out.println(dhm.print(p1.normalizedStandard()));
    System.out.println(dhm.print(p2.normalizedStandard()));
    System.out.println(dhm.print(p3.normalizedStandard()));

Produces output::

1 hour and 1 second

33 minutes and 20 seconds

3 days and 9 hours and 31 minutes and 38 seconds

Answer 2

I like the previous answer, but this option looks more readable:

PeriodFormat.getDefault().print(new Period(0, 0, yourSecondsValue, 0)
    .normalizedStandard())
