// Java Program to Find the difference
// between Two Time Periods

// Importing the Date Class from the util package
import java.util.*;

// Importing the SimpleDateFormat
// Class from the text package
import java.text.*;

public class GFG {

public static void main(String[] args) throws Exception
{

// Dates to be parsed
String time1 = “18:00:00”;
String time2 = “7:30:50”;

// Creating a SimpleDateFormat object
// to parse time in the format HH:MM:SS
SimpleDateFormat simpleDateFormat
= new SimpleDateFormat(“HH:mm:ss”);

// Parsing the Time Period
Date date1 = simpleDateFormat.parse(time1);
Date date2 = simpleDateFormat.parse(time2);

// Calculating the difference in milliseconds
long differenceInMilliSeconds
= Math.abs(date2.getTime() – date1.getTime());

// Calculating the difference in Hours
long differenceInHours
= (differenceInMilliSeconds / (60 * 60 * 1000))
% 24;

// Calculating the difference in Minutes
long differenceInMinutes
= (differenceInMilliSeconds / (60 * 1000)) % 60;

// Calculating the difference in Seconds
long differenceInSeconds
= (differenceInMilliSeconds / 1000) % 60;

// Printing the answer
System.out.println(
“Difference is ” + differenceInHours + ” hours ”
+ differenceInMinutes + ” minutes ”
+ differenceInSeconds + ” Seconds. “);
}
}

Output:

Difference is 10 hours 29 minutes 10 Seconds.
