第一个使用平台，感觉有点懵了。题目跟一般的也不一样。

ACcode:

import java.util.Scanner;

public class Time {

	public String whatTime(int seconds){
		
		
		int h = seconds/(60*60);
		seconds = seconds - h*(60*60);
		int m = seconds/60;
		seconds = seconds - m*60;
		int s = seconds;
		
		return h+":"+m+":"+s;
	}
	public static void main(String[] args) {
		Scanner cin = new Scanner(System.in);
		Time time = new Time();
		int seconds = cin.nextInt();
		System.out.println(time.whatTime(seconds));
	}
}

第一次在这上面做题。
