Convert number of seconds into HH:MM (without seconds) in Java

Question

I\'m aware that you can use DateUtils.formatElapsedTime(seconds) to convert a number of seconds into a String with the format HH:MM:SS

Answer 1

MadProgrammer has already provided a good Java 8 answer (which will work in Java 6 and 7 too when you use the ThreeTen Backport). In Java 9 still a bit more of the calculation can be done in the library:

    int seconds = 3665;
    Duration dur = Duration.ofSeconds(seconds);
    String formatted = String.format("%d:%02d", dur.toHours(), dur.toMinutesPart());
    System.out.println(formatted);

Output:

1:01

The toMinutesPart method and other toXxxPart methods were introduced in Java 9.
