Question

HELP IN JAVA: WHILE LOOP: Write a program that asks the user to enter a number of seconds. This number should be less than or equal to 32767 because that is the largest number pep8 can handle. Your program should then output the number of hours, minutes, and seconds on the planet of Crypton, where there are 64 seconds in a minute and 32 minutes in an hour.

Answer 1

import java.util.Scanner;

public class TimeInCrypton {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter number of seconds(<32767): ");
        int seconds = in.nextInt();
        while (seconds < 0 || seconds >= 32768) {
            System.out.print("Invalid. Enter number of seconds(<32767): ");
            seconds = in.nextInt();
        }
        int s = seconds;
        int hours = seconds / (64*32); seconds %= (64*32);
        int minutes = seconds / 64;
        seconds = seconds % 64;

        System.out.println(s + " seconds is " + hours + " hours, " + minutes + " minutes and " + seconds + " seconds");
    }
}
