Calculate Difference between Two Time Periods in Java

TIME DIFFERENCE: 6:10:49 - 11:44:73 = 5:34:24

• The given program shows a class called Time which has three data members namely hour, min, and sec. These data members true to their name, represent just the same of a provided time.
• The constructor of this class ‘Time’ assigns values for these three given data members.
• For the main functionality of this program which refers to finding out the difference between the two time frames, difference() function is created. It uses mathematical calculations to find out the time difference between the two parameters which it takes and then returns the result as an object of the type Time class.
