Simple Select Statement Error

Question

Hello,
I want to print user from my database, this is the code:
                      System.out.println("user:\n"); user = sc.next(); System.out.println("password:\n"); psw = sc.next();                                                     Statement s = conn.createStatement (); s.executeQuery("SELECT usr, pass FROM log WHERE usr=''"+user+" AND pass=''"+psw);                       ResultSet rs = s.getResultSet ();                       if (s.getMoreResults()){                           System.out.println("works");                       }                       else if (!s.getMoreResults()){                           System.out.println("doesn't");                           System.exit(1);                       }                         while (rs.next ())   {             String nameVal = rs.getString ("user");       String catVal = rs.getString ("pass");       System.out.println (                       "name = " + nameVal               + " pass = " + catVal);       ++count;   }
the connection is established, but it doesn't print anything when I enter data in it [ admin "1234" which exists in the db ], any idea what could be wrong? I have to mentioned that I'm a little bit fresh in Java databases.

hey I sorted out! = )
ResultSet rs = s.getResultSet ();
   if (rs.next()) {
     do {
      String nameVal = rs.getString ("lnum");
       String catVal = rs.getString ("passwd");
       System.out.println (
                "name = " + nameVal
               + " password = " + catVal);
     //  System.out.println("Full access granted ");
JOptionPane.showMessageDialog(frame,
    "Welcome in LYITstorage",
    "Welcome",
    JOptionPane.INFORMATION_MESSAGE);
Desktop.getDesktop().browse(new java.net.URI("www.google.com"));
        } while (rs.next());
   else{
       JOptionPane.showMessageDialog(frame,
    "Username or password are incorrect\n " +
     "If You don't have an account please\n press the regestration link",
    "Regestration problem",
    JOptionPane.ERROR_MESSAGE);

try
                      System.out.println("try");
                         Statement s = conn.createStatement ();
                         System.out.println("statement");
                         int count =0;
                         boolean temp;
                         String query =   "INSERT INTO log (passwd, name,surname,lnum) VALUES ('"+pa+"', '"+n+"', '"+sn+"','"+nu+"')" ;
                         System.out.println("test");
                      count=  s.executeUpdate(query);
                        System.out.println(query);
                       System.out.println(count);
                         ResultSet rs = s.getResultSet ();
                         if(rs.next()){
                             JOptionPane.showMessageDialog(frame,
                            "Welcome ",
                            "Welcome",
                             JOptionPane.INFORMATION_MESSAGE);
                        else   {
       JOptionPane.showMessageDialog(frame,
    "User already exists","error",
    JOptionPane.ERROR_MESSAGE);
   }
