Is there an interface to replace Vector?

[Peter Chatterton]

I have a class extending Vector, but I want it to extend another base class
that contains variables. Can I implement some interfaces to do the same
thing?

The following from the Vector API makes me think I'm out of luck:

public class Vector
extends AbstractList
implements List, Cloneable, Serializable

But I would appreciate another opinion.

Assuming I'm right, is this a feature or a flaw of Java?

Thanks,
Peter.

Hi Peter,

Is it an idea to write a "Wrapper" class that contains the Vector (or other
base class) then write your own methods to put and get the variables.

Something like:

public class WrapperClass (BaseClass base)
{
private BaseClass privateBaseClas s;

public Iterator getIterator()
{
Your code to return an Iterator;
}

public ArrayList getArryList()
{
Your code to return an ArrayList;
}

public Object getObject(Objec t key)
{
Your code to return the object belonging to key
}

......... etc ........

public WrapperClass(Ba seClass base)
{
privateWrapperC lass = base;
}

}

Then use it like:
WrapperClass wrapped = new WrapperClass(<y our base class object>)

for (Iterator i = wrapped.getIter ator(); i.hasNext();)
{
Do your stuff......
}

Hope it gives you ideas.....

Regards,

Frank.
