Java regular expression validation mailbox phone number example

The following code USES regular expressions to validate the input format to include the authentication mailbox and the authentication mobile phone number

package com.firewolf.utils;
import java.util.regex.Matcher;

import java.util.regex.Pattern;
/**

 *  Use regular expressions to validate the input format 

 * @author liuxing

 */

public class RegexValidateUtil {

 public static void main(String[] args) {

  System.out.println(checkEmail("14_8@qw.df"));

  System.out.println(checkMobileNumber("071-3534452"));

 }

 /**

  *  Validation email 

  * @param email

  * @return

  */

 public static boolean checkEmail(String email){

  boolean flag = false;

  try{

    String check = "^([a-z0-9A-Z]+[-|_|\.]?)+[a-z0-9A-Z]@([a-z0-9A-Z]+(-[a-z0-9A-Z]+)?\.)+[a-zA-Z]{2,}$";

    Pattern regex = Pattern.compile(check);

    Matcher matcher = regex.matcher(email);

    flag = matcher.matches();

   }catch(Exception e){

    flag = false;

   }

  return flag;

 }

 

 /**

  *  Verify phone number 

  * @param mobiles

  * @return

  */

 public static boolean checkMobileNumber(String mobileNumber){

  boolean flag = false;

  try{

    Pattern regex = Pattern.compile("^(((13[0-9])|(15([0-3]|[5-9]))|(18[0,5-9]))\d{8})|(0\d{2}-\d{8})|(0\d{3}-\d{7})$");

    Matcher matcher = regex.matcher(mobileNumber);

    flag = matcher.matches();

   }catch(Exception e){

    flag = false;

   }

  return flag;

 }

}
