This is in Java

Design a User-Defined class called SimpleDate.java with three attributes day, month and year. A date object represents a date according to the Gregorian calendar. The class should provide the following:

Default and parametric constructors.

getMonth( ), getDay( ), getYear( ) methods.

setYear( )

setMonth( ) check if the month value is between 1 12 before assigning to month

setDay( ) this method will check the month first to validate whether the value that will be assigned to day is legal. Example, a value of 31 for the day for month 11 (November) is invalid and should not be assigned and should throw an IllegalArgumentException as shown below: throw new IllegalArgumentException( appropriate error message should go here ); If the year is a leap year than a value of 29 for the day and a value of 2 for the month(February) is valid. To determine whether a year is a leap year, use the GregorianCalendar class that is part of the util package. This class has a non-static method called isLeapYear( ).

Implement toString( ) and equals( ) method.

Make sure to keep make your output verbose and comment your code.

Next, create a client program SimpleDateTest.java with the main method( ). In the program prompt the user for a day, month, and year to create a Date object and display date values using the get methods and demonstrate the working of the set methods. Create at least 5 appropriate test cases to test the set methods of the Date class. Use the below format for Test Cases:

Test Case	Inputs	Expected Output	Actual Output
1	Year = 2012 Month = 2 Day = 28 to the constructor followed by call to the toString( ) method	2/28/2012
2	Year = 2013 Month = 3 Day = 32 to the constructor followed by call to the toString( ) method	IllegalArgumentException generated with the message Day value cannot be greater than 31
