Vector troubles

Question

Hi everyone, I'm hoping someone can help me out...
I have a Vector in which I store arrays, in the arrays I would like to put elements of a database. When I put the elements in the arrays (which already are stored in the vector), everything seems to be alright (I have printed it out during the reading of the db and storing the elements) but when I want to restore the elements it seems as if all the elements of the String class have been replaced by the last String element read and analogous for int elements.
Here is a piece of my code:
contents is the vector
result is a ResultSet I get from executing a query
type is an array wich contains the types of each column in my db
for (int i = 0; result.next (); i++)
for (int j = 0; j < contents.size (); j++)
if (type [j] == Types.INTEGER)
((int []) contents.elementAt (j)) = result.getInt (j+1);
else
((String []) contents.elementAt (j)) [i] = result.getString (j+1);
thx for helping me out!!

Vectors don't hold objects, but references to object. You're creating one object, and adding a reference to that one object to the Vector over and over again. That's why all the elements are the same.
