Variable vector names???

Question

hi,
i'm new to this java action, so sorry if this is really obvious, but i can't get this to work.
i need to assign information to a different vector within a loop so for example>>>>>>
String[] nameofvector = { "nameVector", "productVector", "typeVector" };
for (int i=1; i<= 3;i++) {
Vector eval(nameofvector) = new Vector(); //i know eval doesn't work but it's
eval(nameofvector).elementAt(i) = nameofvector[i] // there so you can see what i'm trying to do
any ideas?
thanks,
ben
btw: this is my 1st post ;)

You can use Hashtable (or one of the other Map classes). It takes a key-value pair, where the key could be the name of your vector, and the value is the vector:
Hashtable vectors = new Hashtable();
vectors.put("nameVector", new Vector());
vectors.put("productVector", new Vector());
vectors.put("typeVector", new Vector());
// to get a named vector:
Vector vector = (Vector)vectors.get("productVector");You could also have an array of vectors, and make constants for the 3 vectors.
public static final NAME_VECTOR = 0;
public static final PRODUCT_VECTOR = 0;
public static final TYPE_VECTOR = 0;
private Vector[] vectors = new Vector[3];
// ... inside the construtor:
for (int x = 0; x < vectors.length; x++) {
  vectors[x] = new Vector();
// to get a vector:
Vector vector = vectors[PRODUCT_VECTOR];
