Answer 2

public class Program {
    public static void main(String[] args) {
        int ms = 317520;

        int hours = (int) ((ms / (1000 * 60 * 60)) % 24);
        int minutes = (int) ((ms / (1000 * 60)) % 60); 
        int seconds = (int) (ms / 1000) % 60;
        int milliseconds = ms - ((hours * 3600000) + (minutes * 60000) + (seconds * 1000));
        
        System.out.println(hours + ":h " + minutes + ":m " + seconds + ":s " + milliseconds + "ms");
    }
}
