Retreiving a value from and SQL query

Question

If anyone can give me sample code or pointers to retreive a value from an sql query, I'd be greatful.
Source code I've muddled together so far:
Class seqNumType = Class.forName(nameOfClass);
Constructor theConstructor = seqNumType.getConstructor(null);
Object seqNumInstance = theConstructor.newInstance(null);
String theStatement = "SELECT value INTO v_seqnum FROM DUAL;";
OracleCallableStatement ocs = (OracleCallableStatement)conn.prepareCall(theStatement);
ocs.registerOutParameter( 1, OracleTypes.NUMBER, 0);
Method method = seqNumInstance.getClass().getMethod("getORADataFactory", null);
seqNumInstance = ocs.getORAData(1, (ORADataFactory)method.invoke(null,null));
ocs.execute();
Problem with this seems to be the ORADataFactory isn't a method of the class, but as I'm thumbling around in the dark here a little, I've no idea where to go from here. Is this just generally overkill anyway?
Suggestions?
Cheers for any help.

Like this:
            ResultSet resultSet=statement.executeQuery("SELECT * FROM TEST");
            while(resultSet.next())
                for(int i=0;i<resultSet.getMetaData().getColumnCount();i++)
                    System.out.print(resultSet.getObject(i+1).toString()+" ");
                System.out.println();
