Array to vector - isn't working.

Question

Hello all.
Firstly, this is not a homework question. I am doing a course which teaches Object Oriented programming which happens to use Java to teach it. I've discovered I like programming in Java and figure I have just enough knowledge to be dangerous, so I have set out on a project of my own.
The app I am building uses a webservice to log into a site and retrieve sports information, then performs calculations based on the information and sends further requests to get stuff done. Your basic webservice app I guess.
The problem I am having at the moment is that I'm trying to populate a vector using a complex type array called EventType which is returned by the service.
I'm not having any problems getting the information back from the service, but I want to use the data returned in a JTable, which means I have to construct a model for the table and it is here that I am striking my problem.
I can access the EventType array and get the information from it easily enough and I can separate the information I want out of it pretty easily as well. What I am having trouble doing is putting the information into a collection of some sort which I can send to my AbstractTableModel.
The EventType array contains four arrays of Strings and Integers. I only need to work with two of them though, so my first thought was to use a HashMap<Integer, String> because the integer will always be unique to that event and can be used as a key. Another way of doing it would be to pass the information over to the table model as a vector, then break it down in the model itself.
I am having trouble iterating over the EventType array and inserting it into whatever collection type I am using though.
Here is the code:
// imports
import com.betfair.publicapi.types.global.v3.EventType;
import java.util.Vector;
// declarations
public static EventType[] sports;
public static Vector sportsVector;
// troublesome code
sports = new EventType[result.getEventTypeItems().getEventType().size()];
System.out.println("Number of sports: " + sports.length);
sportsVector = new Vector();
System.out.println("Made the vector...");
for (int s = 0; s < sports.length; s++)
    System.out.println("Putting entry number " + s + " in now.");
    sportsVector.addElement(sports[s]);
    System.out.println("Added sport number " + s);
System.out.println("Filled the map...");As you can see I have sprinkled the code with println's to track down where the problem is. The code works perfectly right up until I see:
System.out.println("Putting entry number " + s + " in now."); the first time it goes through the loop.
Whereupon the entire thing stops. There is no crash, there is no warning in the output window (I am using netbeans), nothing happens at all. The same thing happens when I try to use a Vector or a Set. I haven't tried a list yet.
I'm fairly sure this is something basic I have missed, but I can't for the life of me figure out what it is.
Any ideas please?

Thanks for your replies guys.
I'm not sure what has happened there, since I didn't change anything except to restart netbeans (started to behave strangely), but suddenly it is filling the vector the way it is supposed to.
I am getting a warning:
Note: C:\Users\alan\Documents\NetBeansProjects\AnotherBF\src\anotherbf\SportsMonitor.java uses unchecked or unsafe operations.
Note: Recompile with -Xlint:unchecked for details.Which I think has to do with declaring a type within the vector. I gave google a scouring and after trying the solution of declaring the type within the addElement method, the whole thing refused to compile.
i.e.
sportsVector.addElement(new EventType(sports[s]));I'm not sure how to fix that.
