The files must be named as follows: <LastNameFirstNameDateDriver.java>.
Example: DeweyKenDateDriver.java (driver program)
Date.java (Date class file)
Ensure you include ALL files required to make your program compile and run.
I would like to see your .java files only.
Proper coding conventions required the first letter of the class start with a capital letter and the first letter of each additional word start with a capital letter.

Overall Requirements
Create a class named Date that stores date values and prints out the date in either a pure numeric format or a name and number format (see sample session for format details).
Date.java class file
¡¤ Date objects should store the date in two int instance variables ©¤ day and month, and it should include the String instance variable, error, initialized with null.
Implement a 1-parameter Date constructor that receives a dateStr string parameter and performs complete error checking on the given dateStr value. The Date constructor is the entity that¡¯s responsible for date error checking. That way, if a Date object is instantiated and if there are no errors, then you¡¯re guaranteed that the Date object holds a legitimate date value. If any kind of error occurs, change the value of the error instance variable to a non-null string value, using an appropriate concatenation of a string constant, input substring, and/or API exception message.
Constructors use the same exception handling rules as methods: In a try block, include the parsing of the month and day substrings and other error-checking logic that will not work if parsing fails.
¡¤ Take into account the actual number of days in each month, but assume that there are always 28 days in February.
¡¤ To extract day and month numbers from the given date string, use String¡¯s indexOf method to find the location of the slash character, and String¡¯s substring method to extract month and day substrings from the input string.
¡¤ Include a method for printing the date with a numeric format. Use the zero-pad flag in a printf method call to get exactly two digits for each month and day.
¡¤ Include a method for printing the date with an alphabetic format.
Include a getError method which returns the value of the error instance variable.

In your driver class, include a loop that repeatedly:
¡¤ Asks the user to enter a date or ¡°q¡± to quit.
¡¤ If the entry is not ¡°q¡±, instantiate a Date object.
¡¤ If the error variable is null:
o Print the date using numeric format.
o Print the date using alphabetic format.
Otherwise, print the value of the error variable.
