DDL:

2.    id INT(11) NOT NULL auto_increment PRIMARY KEY,
3.    name VARCHAR(100) NOT NULL default ''
4. );

6.CREATE TABLE email (
7.    id INT(11) NOT NULL,
8.    address VARCHAR(100) NOT NULL
9.);

2.
3.import java.util.Set;
4.
5.public class User {
6.
7.    private Integer id;
8.    private String name;
9.    private Set<String> emails;
10.

15.        return id;
16.    }
17.    public void setId(Integer id) {
18.        this.id = id;
