while(rs.next()){
     System.out.println("rs.getInt"empno"");
     System.out.println("rs.getString"empname"");
     }}}

Answer 1

I think this is better:this would be much better:
package cruft;
import java.sql.*;
public class DB
   private static final String DRIVER = "sun.jdbc.odbc.JdbcOdbcDriver";
   private static final String URL = "jdbc:odbc:bharat";
   private static final String SELECT_SQL = "select empno,empname from emprecord";
   public static void main(String[] args)
      Connection conn = null;
      Statement stmt = null;
      ResultSet rs = null;
      try
         Class.forName(DRIVER);
         conn = DriverManager.getConnection(URL);
         stmt = conn.createStatement();
         rs = stmt.executeQuery(SELECT_SQL);
         while (rs.next())
            int empno = rs.getInt(1);
            String empname = rs.getString(2);
            System.out.println("emp #   : " + empno);
            System.out.println("emp name: " + empname);
      catch (ClassNotFoundException e)
         e.printStackTrace();
catch (SQLException e)///////////// CHANGE HERE
         e.printStackTrace();
catch (Exception e)////////////// CHANGE HERE (Optional)
         e.printStackTrace();
      finally
         try { if (rs != null) rs.close(); } catch (Exception e) { e.printStackTrace(); }
         try { if (stmt != null) stmt.close(); } catch (Exception e) { e.printStackTrace(); }
         try { if (conn != null) conn.close(); } catch (Exception e) { e.printStackTrace(); }
}
