// Time class : Hours, Minutes and Seconds

// Write a program that asks the user to enter seconds as integer.

// The program should compute and display the number of hours,

// number of minutes and number of seconds in that seconds.

// For example if user enters 4205 seconds as a input called totSeconds.

// The answer should be

// Hours : 1

// Minutes : 10

// Seconds : 5

// These calculations can be done in a method name: conversion1() which

// will also display the result as Hour,minutes and seconds.

// Similarly- if user input is Hour, Minute and Second then write another method

// conversion2() which will have these three parameters and

// the conversion2 method will compute and display the totSeconds.

// Pseudocode

// class Time

// variables

// - hours

// - minutes

// - seconds

// methods

// - constructor 1 if totseconds entered

// - constructor 2 if h/m/s entered

// - conversion 1: totseconds to hms

// - conversion 2: hms to totseconds

// class timeconversions:

// methods

// - main

// - input user choice: totsecs or hms

// - construct a time obj resp.

// - print req. output
