How to show time difference of hours which are greater than 24 hours?

Question

I'm facing difficulties to show the time time difference in hours where hours are greater than 24. Right now I'm using the following in iReport

(new SimpleDateFormat("dd':'HH':'mm':'ss")).format(new Date($V{avgDuration}.longValue()*1000))

where $V{avgDuration} is a variable in jrxml file which is the average time difference between two dates in seconds. Here it shows the 1 day 1 hour but I want it to be 25 hour. What should I do?

Answer 1

I've solved the problem using PeriodFormatterBuilder. But for this, I need to use joda-time library.

In the expression editor of the text box in jrxml file, just wrote the following:

new org.joda.time.format.PeriodFormatterBuilder()
        .printZeroAlways()
        .minimumPrintedDigits(2)
        .appendHours().appendSeparator(":")
        .appendMinutes().appendSeparator(":")
        .appendSeconds()
        .toFormatter()
        .print(new org.joda.time.Period(
            $V{avgDuration}.longValue()*1000))
