SQL + Java

Here's the code to my program:
<start>
import java.io.*;
import java.net.*;
import java.sql.*;
import java.util.*;

public class feh {

private static BufferedReader input = new BufferedReader
(new InputStreamReader(System.in));


public static void main(String argv[]) throws Exception {


Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");

String url = "jdbc:odbc:oracle";
String username, password, sqlQuery;

System.out.print("\nEnter username: ");
username = input.readLine();
System.out.print("\nEnter Password: ");
password = input.readLine();
System.out.print("\nEnter SQL Query: ");
sqlQuery = input.readLine();
Connection con = DriverManager.getConnection(url, username, password);

Statement stmt = con.createStatement();

ResultSet rs = stmt.executeQuery(sqlQuery);

while (rs.next()) {
String s1 = rs.getString(1);
String s2 = rs.getString(2);
System.out.println(s1 + "\t" + s2);

}
con.close();
System.out.print("\nClosed connection");
}//end of main()
}//end of feh
<stop>

Right, if my sql query is "SELECT * FROM Emp;" the while statement will print the first two columns of the table Emp back to me. That's fine i understand that. But i was wondering is there a way to print the entire results gotten from "SELECT * FROM Emp;", every column for each row in the table Emp. I will supply Emp if needs be.
