ResultSet to Integer array in Java

Bad code. I'd recommend a PreparedStatement:

PreparedStatement ps = connection.prepareStatement("SELECT ores FROM testtable WHERE nicknames= ?");
ps.setString(1, nickname);
ResultSet rs = ps.executeQuery();
List<Integer> values = new ArrayList<Integer>();
while (rs.next()) {
    String ores = rs.getString("ores");
    String [] tokens = ores.split("\\s+");
    for (int i = 0; i < tokens.length; ++i) {
        values.add(Integer.valueOf(tokens[i]));
    }
}

The ResultSet is the result of yourr query, if you want to transform it to an ArrayList or a simple Integer array, you can iterate over the ResulstSet and add all the non-null Object to your ArrayList or array. This is a simple solution...

Vector<Integer> ores = new Vector<Integer>();
rs.beforeFirst();
while(rs.next()){ores.add(rs.getInt(1));}
Integer[] vals = ores.toArray(new Integer[0]);

Maybe something like:

rs.last(); 
rowcnt = myResultSet.getRow(); // get row no.
rs.beforeFirst();

int i = 0;  
Integer[] options = new Integer[rowcnt];  
while (rs.next()) {  
  options[i] = Integer.parseInt(rs.getString(i));  
  i++;  
}
