PeriodFormatter - How to prepend 0s if the hours or minutes happens to be a single digit number?

Question

When I use PeriodFormatter as below

PeriodFormatter formatter = new PeriodFormatterBuilder().appendHours()
                .appendLiteral(":").appendMinutes().appendLiteral(":")
                .appendSeconds().toFormatter();

I get the output as 4:39:9 Which means 4 hrs 39 mins and 9 seconds.

How to modify the formatter to produce 04:39:09? Thanks

Add .printZeroAlways() and .minimumPrintedDigits(2):

    PeriodFormatter formatter = new PeriodFormatterBuilder()
        .printZeroAlways()
        .minimumPrintedDigits(2)
        .appendHours()
        .appendLiteral(":")
        .appendMinutes()
        .appendLiteral(":")
        .appendSeconds()
        .toFormatter();

Take a look at minimumPrintedDigits. It should do what you want.
