简单了解JavaBean作用及常用操作

package com.mail.bean;

public class Email {
	private String mailAdd;
	private boolean test;

	public Email() {}
	 
	public Email(String mailAdd) {
		this.mailAdd = mailAdd;
	}

	public boolean isEamil() {
		// 正则表达式，定义邮箱格式
		String regex = "\\w+([-+.']\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*"; 
		// matches()方法可判断字符串是否与正则表达式匹配
		if (mailAdd.matches(regex)) { 
			test = true;
		}
		return test;
	}
	public String getMailAdd() {
		return mailAdd;
	}
	public void setMailAdd(String mailAdd) {
