在员工管理的GUI练习中加入数据验证。也就是在添加对象进数组之前，先作数据合法性的验证，数据合法再作添加。

姓名：2个以上的字母或汉字

性别：必须是男或女

年龄：必须为数字

电话：13、15、18开始的11位数字 或者  028-99823345

1、员工类

 1 public class Staff {
 2     private String name ;
 3     private int age ;
 4     private String sex ;
 5     private String tel ;
 6
 7
 8
 9     public String getName() {
10         return name;
11     }
12     public void setName(String name) {
13         this.name = name;
14     }
15     public int getAge() {
16         return age;
17     }
18     public void setAge(int age) {
19         this.age = age;
20     }
21     public String getSex() {
22         return sex;
23     }
24     public void setSex(String sex) {
25         this.sex = sex;
26     }
27     public String getTel() {
28         return tel;
29     }
30     public void setTel(String tel) {
31         this.tel = tel;
32     }
33
34 }
