1. Create a parent class named Time with at least 3 private members of int date type: hour, minute, and second. You should use the calendar to set up its hour, minutes, and second.
2. Create a test class to printout your current hour, minute, and second.
3. Create a child CourseTime with six private members, int lengthOfOS, int OSStartHour, int lengthOfSecurity, int SecurityStartHour, int lengthOfForensics, int ForensicsStartHour, and 6 public get/set methods to manipulate them. The length of each course could be in hour too. For example, OSs course time is 14:00 - 16:00 in 24 hour format, the value of lengthOfOS is 2 while OSStartHour is 14.
4. Printout the class time for each of the three courses(e.g., os, security, forensics) in the test class.

Then, you need to write a method in the CourseTime class to determine if the current time is course time and determine which Course (os, security, forensics) you should be in. Printout the results to see which class you should be in right now.
