Newbie question about using vectors and arrays

Question

I'm fairly new to JME development and java in general. I need some help in regards to Vectors and 1 dimensional arrays. I'm developing a blackberry midlet and am saving the queried info i pull back from my server side application with each record saved into the array and subsequently each array saved as an element in the vector, thereby creating a 2D "array".
However I'm having a problem accessing the elements in the array. Here is a sample of what I mean and where I get stuck:
Vector _dataTable = new Vector(1, 1);
String[] r1 = {"a", "b", "c", "d"};
String[] r2 = {"1", "2", "3", "4"};
_dataTable.addElement(r1);
_dataTable.addElement(r2);
Object temp = _dataTable.elementAt(0); //Save the element as an new object for useNow how do I access the particular indexes of the element of the temp object? Do i need to caste it to an array? Is there another more efficient/easier way I should be storing my data? Any help would be great!

Answer 1

Thanks for the feedback newark. I have this scenario below:
// Class for my 1D array
public class OneRecord {
    private String[] elementData = new String[4];
    public OneRecord() {   
        elementData[0] = null;
        elementData[1] = null;
        elementData[2] = null;
        elementData[3] = null;
    public OneRecord(String v1, String v2, String v3, String v4) {   
        elementData[0] = v1;
        elementData[1] = v2;
        elementData[2] = v3;
        elementData[3] = v4;
    public void setElement(int index, String Data) {
        elementData[index] = Data;
    public String getElement(int index) {
        return elementData[index];
} Then in my main app I have:
Vector _dataTable = new Vector(1, 1);
OneRecord currRecord = new OneRecord("a", "b", "c", "d");
_dataTable.addElement(currRecord);
OneRecord temp = (OneRecord)_dataTable.elementAt(1);
System.out.println(temp.getElement(0)); Are there more efficient data structures out there to save queried data from a server side app? Like I said, i'm still trying to learn the most efficient techniques of coding...esp for the Blackberry. Any suggestions would be great!
