Thanks for the response, but I still don't follow (I'm thickheaded sometimes). The concrete classes that extend the abstract class have their own constructors. How can they implement the abstract class' constructor?

Hi, I'm still learning java and have a question about abstract classes: If an abstract class cannot be instantiated, why does it have a constructor(s)? Take, for example, the Writer class from the java.io package. It has two. Thanks for any help.

Now I understand. I really appreciate your help. Thanks!

So, you're saying that the statement: robots[index] returns only the reference and not the object itself, which would require a cast (because the reference is of type Robot which doesn't implement Locomotion)? And, that the statement: Locomotion loco = robotB returns the object itself...

I am currently in the process of teaching myself Java, and have a question concerning assigning array components to an interface reference. The complete program listing is below, but here is the portion that I have a question about: for (int index = 0; index < 7; index++) { if (robots[index]...

Hi, The strContent parameter in the code below receives its value from a Memo field in an Access database. If I open the recordset with an adOpenForwardOnly cursor, no matter what value I send to strContent (empty string, Null, or a valid string), I get the error - Microsoft VBScript runtime...

I am attempting to add a reference to winsock.dll to use the Winsock control to do some email programming in Access. However, Winsock is not listed in the Available References listbox on the References dialog (or is it? Am I looking for the wrong name?). I clicked Browse, and tried to manually...

Thank you! I'll give it a shot.

Does anyone know how to prevent the security messages that pop up when sending email from Access? The messages read: &quot;A program is trying to access e-mail addresses you have stored in outlook. Do you want to allow this?&quot; and &quot;A program is trying to automatically send e-mail on...
