How can I “pretty print” a Duration in Java?

Question

Does anyone know of a Java library that can pretty print a number in milliseconds in the same way that C# does?

E.g., 123456 ms as a long would be printed as 4d1h3m5

Java 9+

Duration d1 = Duration.ofDays(0);
        d1 = d1.plusHours(47);
        d1 = d1.plusMinutes(124);
        d1 = d1.plusSeconds(124);
System.out.println(String.format("%s d %sh %sm %ss", 
                d1.toDaysPart(), 
                d1.toHoursPart(), 
                d1.toMinutesPart(), 
                d1.toSecondsPart()));
