unchecked conversion problems

843793Oct 14 2004 — edited Oct 17 2004

I'm using a Vector where I'm storing some Vectors containing some Integers. When I'm compiling I'm getting the following warning:

HHH.java:130: warning: [unchecked] unchecked conversion
found   : java.util.Vector
required: java.util.Vector<java.util.Vector>
                        cellsInformation = (Vector)dats.get("Cells Information ASquad");

where dats and cellsInformation are as follows:

HashMap<String, Vector> dats = new HashMap<String, Vector>();
Vector<Vector> cellsInformation = new Vector<Vector>();

How can I get this Vector out of the HashMap without a warning (even so, how does one get an element out of a Vector without warnings like "unchecked call to...")
