Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.*;
 public class Javaexcercise {
 public static void main(String[] args)
    {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter seconds: ");
        int seconds = in.nextInt(); 
        int a = seconds % 60;
        int b = seconds / 60;
        int c = b % 60;
        b = b / 60;
        System.out.print( b + ":" + c + ":" + a);
        System.out.print("\n");
    }    
 }

Result
