Hi Jason,
you can build your own class extended from Object. Store String members in
Vector object inside the class. Define your own elementAt, etc. methods.
For example:
public class StringVector extends Object {
  Vector strings  = new Vector();

  public String elementAt(int index) {
    return (String)strings.elementAt(index);
  }

...
}
