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

public class Staff {
    private String name ;
    private int age ;
    private String sex ;
    private String tel ;
    

    
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public int getAge() {
        return age;
    }
    public void setAge(int age) {
        this.age = age;
    }
    public String getSex() {
        return sex;
    }
    public void setSex(String sex) {
        this.sex = sex;
    }
    public String getTel() {
        return tel;
    }
    public void setTel(String tel) {
        this.tel = tel;
    }
    
}

 2、窗体

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JFrame;
import javax.swing.JOptionPane;

import JLabelAndJButton.MyButton;
import JLabelAndJButton.MyTxt;

public class MainJFrame extends JFrame{

    private MyTxt workSex = new MyTxt("性别", 60, 160, this);
    private MyTxt workTel = new MyTxt("电话", 60, 220, this);
    
    private MyButton addButton = new MyButton("添加", 40, 280, this);
