hi, I think you should mention your exact problem or atleast give a clear idea of what exactly you want to ask...... FYI Vector class is an important class belonging to the Collection framework. So you should have a clear idea of its api and its position in the class hierarchy for the collection framework, the interfaces it implements for 1.4 etc..... hope that helps, rahul

Vector is a legacy class, outside the Collection interface. Regarding all the legacy classes (Dictionary, Hashtable, Properties, Stack, Vector), you should definitely know the differences as compared to the collection interface implementations, wrt synchronization and class hierarchy. This will also point you to the fact that Vector has been made compatible with the Collection interface by extending the AbstractList. Anyway, IMHO, knowing the API details of the legacy classes is not required. Thanks, Sudd
Ah well... you actually *can* have a question on Vector. Or Hashtable. : ) You might, for example, need to know how the newer counterparts, ArrayList and HashMap, for example, are different from Vector and Hashtable. Besides synchronization, you should look at the difference between Hashtable and HashMap with respect to a null key and null values : ) That's a hint... cheers, Kathy

Thanks I think I will have a lot of work to do to be prepared .
I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
