Return both user name and password

Question

hi
I have small code
public String validateUser(String userId, String password)
throws SQLException, ClassNotFoundException{
String returnString = null;
Connection con=null;
  //get free connection from pool
   con =connectionPool.getConnection();
      Statement       stmt = con.createStatement(
                       ResultSet.TYPE_SCROLL_SENSITIVE,
                       ResultSet.CONCUR_READ_ONLY);
String sql = "select password from users where Name='"+userId+"' and password='"+password+"'";
ResultSet rs = stmt.executeQuery(sql);
if (rs.next())
returnString = rs.getString("password");
connectionPool.returnConnection(con);
stmt.close();
con.close();
return returnString;
}if I want to return both User Id and Password, How should I modify the code.
Thank you!

Hi TMary,
I think you should make wrapper class that contains userID and Password because as we are programmer knowledge, we cant return 2 objects! So maybe you should make wrapper class like
class User
public userName;
public password;
you can also make private and make public get and set method
I hope that can help you!
