In Java, Format Milliseconds To Hours:Minutes:Seconds
import java.util.Scanner; public class TimeFormat{ public static String convertMillis(long millis){ int hours = (int) ((millis / (1000*60*60))); int minutes = (int) ((millis / (1000*60)) % 60); int seconds = (int) (millis / 1000) % 60 ; return String.format("%d:%d:%d", hours, minutes, seconds); } public static void main(String[]args){ System.out.print("Enter time in milliseconds: "); long millis = new Scanner(System.in).nextLong(); System.out.println(convertMillis(millis)); } }
