Java convert seconds to minutes hours and days

Question

The output should look like this  it is a good idea to echo back the input   You entered 500 000 seconds  which is 5 days  18 hours  53 minutes and 20 seconds   5 days 18 53 20 hours   So can you guys tell me how I should do it  what is the easiest way to understand and do it  please help guys  I m really stuck  also he said  no hard coding  which I m not exactly sure what it is but I think he wants us to assign them constants

Thanks guys for all the help  I really appreciate but I actually did some thinking and start doing some pseudo code and came up with this   import java util Scanner    public class Project    public static void main String   args         variable declaration   Scanner scan   new Scanner System in   final int MIN   60  HRS   3600  DYS   84600  int input  days  seconds  minutes  hours  rDays  rHours     input  System out println  Enter amount of seconds     input   scan nextInt        calculations days   input DYS  rDays   input DYS  hours   rDays HRS  rHours   rDays HRS  minutes   rHours MIN  seconds   rHours MIN     output if  input  gt   DYS        System out println input     seconds equals to     days     days     hours     hours     minutes     minutes     seconds     seconds       else if  input  gt   HRS  amp  amp  input  lt  DYS        System out println input     seconds equals to     hours     hours     minutes     minutes     seconds     seconds       else if  input  gt   MIN  amp  amp  input  lt  HRS        System out println input     seconds equals to     minutes     minutes     seconds     seconds       else if  input  lt  MIN        System out println input     seconds equals to seconds       scan close             I know it looks really noobie but keep in mind I m still new not just Java but programming entirely  and who knew pseudo code was actually really helpful

An example using built in TimeUnit   long uptime   System currentTimeMillis     long days   TimeUnit MILLISECONDS      toDays uptime   uptime -  TimeUnit DAYS toMillis days    long hours   TimeUnit MILLISECONDS      toHours uptime   uptime -  TimeUnit HOURS toMillis hours    long minutes   TimeUnit MILLISECONDS      toMinutes uptime   uptime -  TimeUnit MINUTES toMillis minutes    long seconds   TimeUnit MILLISECONDS      toSeconds uptime

You can use the Java enum TimeUnit to perform your math and avoid any hard coded values  Then we can use String format String  Object     and a pair of StringBuilder s  as well as a DecimalFormat to build the requested output  Something like   Scanner scanner   new Scanner System in   System out println  Please enter a number of seconds     String str   scanner nextLine   replace            trim    long secondsIn   Long parseLong str   long dayCount   TimeUnit SECONDS toDays secondsIn   long secondsCount   secondsIn - TimeUnit DAYS toSeconds dayCount   long hourCount   TimeUnit SECONDS toHours secondsCount   secondsCount -  TimeUnit HOURS toSeconds hourCount   long minutesCount   TimeUnit SECONDS toMinutes secondsCount   secondsCount -  TimeUnit MINUTES toSeconds minutesCount   StringBuilder sb   new StringBuilder    sb append String format   d  s     dayCount   dayCount    1     day             days     StringBuilder sb2   new StringBuilder    sb2 append sb toString     sb2 append String format   02d  02d  02d  s   hourCount  minutesCount          secondsCount   hourCount    1     hour     hours     sb append String format   d  s     hourCount   hourCount    1     hour             hours     sb append String format   d  s and    minutesCount           minutesCount    1     minute     minutes     sb append String format   d  s    secondsCount           secondsCount    1     second     seconds     System out printf  You entered  s seconds  which is  s   s  n           new DecimalFormat          format secondsIn   sb  sb2     Which  when I enter 500000 outputs the requested  manual line break added for post  -  You entered 500 000 seconds  which is 5 days  18 hours   53 minutes and 20 seconds   5 days  18 53 20 hours

You should try this  import java util Scanner   public class Time converter        public static void main String   args             Scanner input   new Scanner  System in           int seconds          int minutes           int hours          System out print  Enter the number of seconds               seconds   input nextInt            hours   seconds   3600          minutes    seconds 3600  60          int seconds output    seconds  3600  60            System out println  The time entered in hours minutes and seconds is             System out println hours      hours      minutes     minutes     seconds output    seconds

Have a look at the class   org joda time DateTime   This allows you to do things like   old   new DateTime    new   old plusSeconds 500000   System out println  Hours       new Hours   - old Hours        However  your solution probably can be simpler   You need to work out how many seconds in a day  divide your input by the result to get the days  and subtract it from the input to keep the remainder  You then need to work out how many hours in the remainder  followed by the minutes  and the final remainder is the seconds   This is the analysis done for you  now you can focus on the code   You need to ask what s he means by  no hard coding   generally it means pass parameters  rather than fixing the input values   There are many ways to do this  depending on how you run your code  Properties are a common way in java

The simpliest way       Scanner in   new Scanner System in       System out println  Enter seconds        int s   in nextInt         int sec   s   60      int min    s   60  60      int hours    s 60  60       System out println hours         min         sec

my quick answer with basic java arithmetic calculation is this   First consider the following values   1 Minute   60 Seconds 1 Hour   3600 Seconds   60   60   1 Day   86400 Second   24   3600      First divide the input by 86400  if you you can get a number greater than 0   this is the number of   days  2 Again divide the remained number you get from the first calculation by 3600  this will give you the number of hours Then divide the remainder of your second calculation by 60 which is the number of Minutes Finally the remained number from your third calculation is the number of seconds   the code snippet is as follows   int input 500000  int numberOfDays  int numberOfHours  int numberOfMinutes  int numberOfSeconds   numberOfDays   input   86400  numberOfHours    input   86400     3600   numberOfMinutes     input   86400     3600     60  numberOfSeconds     input   86400     3600     60      I hope to be helpful  to you

It should be like       public static void calculateTime long seconds                int day    int TimeUnit SECONDS toDays seconds                       long hours   TimeUnit SECONDS toHours seconds  -  day  24               long minute   TimeUnit SECONDS toMinutes seconds  -  TimeUnit SECONDS toHours seconds   60               long second   TimeUnit SECONDS toSeconds seconds  -  TimeUnit SECONDS toMinutes seconds   60                System out println  Day     day     Hour     hours     Minute     minute     Seconds     second                Explanation   TimeUnit SECONDS toHours seconds  will give you direct conversion from seconds to hours with out consideration for days  Minus the hours for days you already got i e  day 24  You now got remaining hours  Same for minute and second  You need to minus the already got hour and minutes respectively
