Connecting to MySql Database via a JDialog

Question

Hello,
I have a JDialog Box that connects the user to a database, the username is taken through a JTextField and passwork through JPassword field the problem is that the password isn't evaluated rightly........... and hence the application ends in an exception. Here is the code of the method which is executed when a button is pressed....
void UserLogin(ActionEvent e) {
  Connection con;
  user = UserName.getText();
  pass = Password.getPassword().toString();
  try{
   Class.forName("com.mysql.jdbc.Driver");
  catch (Exception se){
  se.printStackTrace();
  try{
   con = DriverManager.getConnection("jdbc:mysql://localhost:3306/test?user="+user+"&password="+Password.getPassword());// I used the variable pass too but it wouldn't work, the variable user is perfect
   System.out.println(con.toString());
   catch (Exception se){
    se.printStackTrace();
   System.out.println(pass);
   this.setVisible(false);
}Please solve this problem for me!

Class String

java.lang.String
All Implemented Interfaces:
Serializable, CharSequence, Comparable<String>
public final class Stringextends Objectimplements Serializable, Comparable<String>, CharSequenceThe String class represents character strings. All string literals in Java programs, such as "abc", are implemented as instances of this class.
Strings are constant; their values cannot be changed after they are created. String buffers support mutable strings. Because String objects are immutable they can be shared. For example:
String str = "abc";
is equivalent to:
char data[] = {'a', 'b', 'c'};
String str = new String(data);
Here are some more examples of how strings can be used:
System.out.println("abc");
String cde = "cde";
System.out.println("abc" + cde);
String c = "abc".substring(2,3);
String d = cde.substring(1, 2);
The class String includes methods for examining individual characters of the sequence, for comparing strings, for searching strings, for extracting substrings, and for creating a copy of a string with all characters translated to uppercase or to lowercase. Case mapping is based on the Unicode Standard version specified by the Character class.
The Java language provides special support for the string concatenation operator ( + ), and for conversion of other objects to strings. String concatenation is implemented through the StringBuilder(or StringBuffer) class and its append method. String conversions are implemented through the method toString, defined by Object and inherited by all classes in Java.
