Problem description

　　 Given a time in seconds t, Asked to use “<H>:<M>:<S>” To represent this time .<H> Time ,<M> Represents minutes , and <S> For seconds , They are all integers and have no leading “0”. for example , if t=0, The output should be “0:0:0”; if t=3661, The output “1:1:1”.

Input format

　　 There is only one line of input , It's an integer t（0<=t<=86399）.

Output format

　　 There is only one line of output , In order to “<H>:<M>:<S>” The time represented by the format of , Exclude Quotes .

The sample input

0

Sample output

0:0:0

The sample input

5436

Sample output

1:30:36

The solution is as follows --

import java.util.Scanner;

public class Main {

    /**
     * Given a time in seconds t, Asked to use “<H>:<M>:<S>” To represent this time .
     * <H> Time ,<M> Represents minutes , and <S> For seconds , They are all integers and have no leading “0”.
     * for example , if t=0, The output should be “0:0:0”; if t=3661, The output “1:1:1”.
     */

    public static void main(String[] args) {
//         receive data
        Scanner scanner = new Scanner(System.in);
//         Acceptance time seconds
        int a = scanner.nextInt();
//         Judge a Is it 1 Hour up
        if (a - 3600 >= 0) {
//            H Hours  a/3600
            int H = a / 3600;
//            F minute Equal to the entered a- Hours = minute + second
            int F = (a - H*3600) / 60;
//            S second   Equal to the entered a- Hours divided by 60 Remainder
            int S = (a - H*3600) % 60;
            System.out.println(H + ":" + F + ":" + S);
        } else {  // Not more than one hour , Find out directly
            int H = 0;
            int F = a / 60;
            int S = a % 60;
            System.out.println(H + ":" + F + ":" + S);
        }

    }
}

The demonstration effect is as follows --

I hope that's helpful !!

Thank you. ！
