 6     private String userName;
 7     private String password;
 8     
 9     
10     
11     public User() {
12         super();
13         // TODO Auto-generated constructor stub
14     }
15     
16     
17     public User(String userName, String password) {
18         super();
19         this.userName = userName;
20         this.password = password;
21     }
22 
23 
24     public int getId() {
25         return id;
26     }
27     public void setId(int id) {
28         this.id = id;
29     }
30     public String getUserName() {
31         return userName;
32     }
33     public void setUserName(String userName) {
34         this.userName = userName;
35     }
36     public String getPassword() {
37         return password;
38     }
39     public void setPassword(String password) {
40         this.password = password;
