How to convert Resulset to two dimenson array

Question

Hello,
I have a Resulset, i want to store it in 2 dimenson array, but i can't.
so I store the resulset in Vector:
Vector row = new Vector();
ResultSet rs = stmt.executeQuery(sql);
ResultSetMetaData meta = rs.getMetaData();
int colCount = meta.getColumnCount();
while(rs.next()){
String[] records = new String[colCount];
     for(int i=0; i<colCount; i++){
          records[i] = rs.getString(i+1);
     row.addElement(records);
However i don't know to convert this Vector to two dimenson array.
Can you help me:
1. store the resulset to two dimenson array
2. or convert the vector that store the resulset to two dimenson array

Answer 1

The problem with storing the result into a two dimensional array directly is that you don't know the size required for the dimensions of the array, so you need to use something that is dynamic ( like a Vector, or a better use would be an ArrayList if you didn't need the container to be thread safe ).
I might suggest something like this:
ArrayList list = new ArrayList();
ResultSet rs = stmt.executeQuery(sql);
ResultSetMetaData meta = rs.getMetaData();
int colCount = meta.getColumnCount();
while(rs.next()){
String[] records = new String[colCount];
for(int i=0; i<colCount; i++){
records[i] = rs.getString(i+1);
row.add(records);
String[][] resultArray = new String[ list.size() ][ colCount ];
for ( int i = 0; i < list.size(); i++ ) {
    resultArray[ i ] = (String[])list.get( i );
}
