Creating a new class

Question

Hi all,
I am new to Java programming and trying to figure out some issues with a class
This is the problem I am trying to solve
1. I am trying to parse a xml and represent it in a JTable
2. I have parsed the xml and stored it in vector of vector formate [rows, columns]
3. Now I need to take input from the vector and fill in the table model
//dataVector is a Vector of Vector
CarrierData cData = (CarrierData) dataVector.elementAt(rowIn);
above statement is one I have issue with, I am not sure how the 'CarrirData' class should be
This is the undestanding I have:
1. as dataVector is a vector of vector, when we do elementAt(row) this would return another vector
2. CarrierData should be a class that has a constructor that has pass Vector as a parameter?
3. Based on the vector elements when we do get of each item this can be returned as column value for the table!
Can some one help me if the approach I am going with is a right way?

all,
I was not able to post my ans earlier today Thanks all for the reply
Here is the mistake what I did, as I mentioned I was trying the following
1. Parse the xml file and store it in a Vector of Vector
2. Read the Vector and add it to a CustomObjectTable model
3. and use this new tableModel to populate the JTable
The mistake I did was storing the data in Vector of Vector, which would work for a a normal DefaultTableModel , but as I was using a wrapper based CustomTableModel this did not work.
according to the code I had pasted
CarrierData cData = (CarrierData) dataVector.elementAt(rowIn);
dataVector is a Vector of Class that would return an Object and when I typecast to the CarrierData, you can acccess all the methods underneath the class to set the column data
So this is how I solved the issue
Parsing the xml
CarrierData rowData = new CarrierData();
if((((Element)nodes).getAttribute(CID)) != null)
rowData.setID(Integer.parseInt(((Element)nodes).getAttribute(CID)));
so the CarrierData class will look as follows
public classs CarrierData
public CarrierData()
protected int getID()
return m_id;
protected void setID(int id)
m_id = id;
protected int m_id;
