Convert negative seconds to hour:minute:second

Question

I would like to create a constructor that takes in seconds and converts it to HH:MM:SS. I can do this pretty easily with positive seconds, but I'm running into some difficulty with negative seconds.

Here is what I have so far:

private final int HOUR, MINUTE, SECOND, TOTAL_TIME_IN_SECONDS;

public MyTime(int timeInSeconds) {
   if (timeInSeconds < 0) {
        //Convert negative seconds to HH:MM:SS
    } else {
        this.HOUR = (timeInSeconds / 3600) % 24;
        this.MINUTE = (timeInSeconds % 3600) / 60;
        this.SECOND = timeInSeconds % 60;
        this.TOTAL_TIME_IN_SECONDS
                = (this.HOUR * 3600)
                + (this.MINUTE * 60)
                + (this.SECOND);
    }
}

If the timeInSeconds is -1 I want the time to return 23:59:59, etc.

Thanks!

Answer 1

if (time < 0)
    time += 24 * 60 * 60;

Add that to the start of the constructor. While insted of IF if you expect big negative numbers.
