JDBCのちょっと質問なんだけれど

import java.sql.*;

public class HelloWorldJDBC {
public static void main(String[] args) {
try {

// ドライバクラスをロード
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
//new sun.jdbc.odbc.JdbcOdbcDriver(); //これでもok

Connection con = DriverManager.getConnection("jdbc:odbc:helloworld");
Statement stmt = con.createStatement();
String sql = "SELECT * FROM HELLO_WORLD_TABLE";
ResultSet rs = stmt.executeQuery(sql);

while(rs.next()){
int no = rs.getInt("NO");
String lang = rs.getString("LANGUAGE");
String msg = rs.getString("MESSAGE");
System.out.println(no + " " + lang + " " + msg);
}
stmt.close();
con.close();
} catch (Exception e) {
e.printStackTrace();
}
}
}
