I thank you for any help you can give with this exercise.
I am reading about user-defined classes and ADT's for the first time.

This exercise asks me to create a UML diagram for a class called MyDate that contains data memebers and a constructor that meet the criteria for the following list. This class is used to initialize instance variables.

The nonstatic integer data members named month, day, and year should be private members so that they cannot be directly manipulated outside of the class.

The nonstatic Boolean data member named good should be a public member so that it can be accessed outside of the class.

The constructor MyDate() should assign to the member variables the values 1 to month, 1 to day, 2006 to year, and the value true to good.

Would the constructor look like this?
+MyDate()
+MyDate(1, 1, 2006, true)

So far I have
______________
MyDate
______________
-month: int
-day: int
-year: int
+good: int
_______________
+MyDate()
+MyDate(1,1,2006,true)

Thank you

Basically, YES. Remove the plus symbol and it should work.

I'm not 100% sure what your wanting to do but heres my thoughts. Note, the code is examples only and would need minor adapting to your situation.


[HIGHLIGHT="Java"]
//assign to a variable: date
date = MyDate(1,1,2006,true);


//check a date using MyDate method
if(date == MyDate(1,1,2006,true){
return true;
else
return false;
}

//NB using return will end the method are return to parent method
[/HIGHLIGHT]


As you should be able to see, the basic answer is yes, depending on how you want to use it.

Hope this helps!
