Create object name using a String variable

Question

Hi,
I�m making a jsp page and I need to add several objects to a vector. The vector's name is arrayGrupo, and the object is Grupo. The problem is that when I create the instance of the object, I cant �give him different names, so the add in the Vector will always be of the same object instance. Is there anyway to create an object name using a variable?
Something like this:
<% if (request.getParameter("grupoNome") != null ) {
                                   nomeG=request.getParameter("grupoNome");
                                   descG=request.getParameter("grupoDesc");
                                   int nG=arrayGrupo.getTamanho(); //size of the array
                                   String xpto=String.valueOf(nG);
                                   Grupo "xpto"= new Grupo(); //here is the problem
                                   xpto.setNomeGrupo(nomeG);
                                   xpto.setDescricao(descG);
                                   xpto.setIdgrupo(arrayGrupo.getTamanho()+1);
                                   arrayGrupo.addGrupo(xpto);
}%>
Thanks

Answer 1

I want to show a list of objects that are stored in a vector. But I also want to add objects to that vector. If I just want to add one object, I can use this code:
<% if (request.getParameter("grupoNome") != null ) {
                                   nomeG=request.getParameter("grupoNome");
                                   descG=request.getParameter("grupoDesc");
                                   Grupo newGrupo = new Grupo(nomeG,descG,arrayGrupo.getTamanho()+1);
                                   arrayGrupo.addGrupo(newGrupo);
%>
What should I do if I want to add more than one object to the vector?
I don�t know if I made myself clear but is quite hard to explain my problem.
Thanks
