By below code i got this duration output:

1 day, 2 hours, 5 minutes

code example:

private String getDurationAsString(Duration duration)
{
    StringBuilder durationAsStringBuilder = new StringBuilder();
    if (duration.toDays() > 0)
    {
        String postfix = duration.toDays() == 1 ? "" : "s";
        durationAsStringBuilder.append(duration.toDays() + " day");
        durationAsStringBuilder.append(postfix);
    }

    duration = duration.minusDays(duration.toDays());
    long hours = duration.toHours();
    if (hours > 0)
    {
        String prefix = Utils.isEmpty(durationAsStringBuilder.toString()) ? "" : ", ";
        String postfix = hours == 1 ? "" : "s";
        durationAsStringBuilder.append(prefix);
        durationAsStringBuilder.append(hours + " hour");
        durationAsStringBuilder.append(postfix);
    }

    duration = duration.minusHours(duration.toHours());
    long minutes = duration.toMinutes();
    if (minutes > 0)
    {
        String prefix = Utils.isEmpty(durationAsStringBuilder.toString()) ? "" : ", ";
        String postfix = minutes == 1 ? "" : "s";
        durationAsStringBuilder.append(prefix);
        durationAsStringBuilder.append(minutes + " minute");
        durationAsStringBuilder.append(postfix);
    }

    return durationAsStringBuilder.toString();
}

Explanation:

By using Duration interface you can easily find the exact String display you want. you just need to reduce the bigger TemporalUnit from current duration.

for example:

1. calculate days
2. reduce days from duration
3. calculate hours
4. reduce hours from duration etc... until u get duration = 0
