Write a java program that prompts the user to input the elapsed time for an event in hours, minutes, and seconds. the program then outputs the elapsed time in seconds.

import java.util.*;

class seconds

{

public static void main (String[] args)

{

    Scanner takeinput=new Scanner(System.in);//creating a scanner object for taking input.

    int hour,min,sec; //declaring 3 variables for hour , minutes and seconds.

    System.out.println("enter hours");

    hour=takeinput.nextInt();//taking input of hours..

    System.out.println("enter minutes");

    min=takeinput.nextInt();//taking input of minutes..

    System.out.println("enter seconds");

    sec=takeinput.nextInt();//taking input of seconds..

    int tot_time_sec=(hour*60*60)+(min*60)+sec; //calculating time in seconds in variable tot_time_sec.

    System.out.println("Total time in seconds is "+tot_time_sec);//pritning total time in seconds..

}

}

For input:

7

20

45

Output is:-

Total time in seconds is 26445..

Explanation:

Above is the code for finding the time in seconds.I have taken three integer variables hour,min and sec for taking input of hours ,minutes and seconds. After taking input i have taken an integer variable tot_time_sec to store the calculated time in seconds and after that printing tot_time_sec.
