Textbook has given a .java file named "date.java", but it is not perfect;
What I have done is the "ExtendedDate.java", which improved the "data.java" that the program will firstly check if the date input from users is valid then store it with the setDate method. Additionally, the "ExtendedDate.java" has the function including of:
1. Set the month.
2. Set the day.
3. Set the year.
4. Return the month.
5. Return the day.
6. Return the year.
7. Test whether the year is a leap year.
8. Return the number of days in the month.
9. Return the numbers of the days passed in the year.
10. Return the number of the days remaining in the year.
11. Calculate the new date by adding a fixed number of days to the date.
"TestExtendedDate.java" will call the methods of "ExtendedDate.java", than print out all the results.
I attached the three java files already;
1. Date.java
2. ExtendedDate.java
3. TestExtendedDate.java

Now what I need you help is to finish an "exception" part of my program. It is to add creating and handling of Exceptions when an attempt is made to create an invalid date. The Exception object must return information to the user about the nature of the problem that occurred.
Please do not change any method's name and the return type, thanks.
Here is a sample run result of my program:
