No, not at all. Suppose you use a Database class that is coming from a specific library that has been developed by a company other than yours. This database class throws an exception if it cannot be constructed.
What will you do ? Ask them to send you the source code because you want to add a specific error handling there ?

Also, if you develop such a class, you sometimes DO NOT WANT to know what to do on an error. Because it is totally bad design to have all the classes know how to manage the errors themselves.
Suppose that you develop this database class. When you use it to connect a specific database in the constructor, you want to check if the connection was successfull or not. If it failed, the only thing you would like to do is connect to another database. Sometimes later in your program, you want to use the same database class to connect another database but there, if it fails, you just want to log the information in a log file because it is not critical. Still in another part of your program, you want to reuse the same class but if the connection fails, you want to display a message box to the user and exit the program.

So, how are you gonna managing all of that in your class constructor ? That will become a big mess. It is not the purpose of the database class to manage the errors because it's simply not its job.
If you fail to understand that, you really should get out of your books and program for real because it seems you are totally disconnected from the 'real world programming'. It's not that hard to understand, is it ?
