Using Java Regular expressions to check mailbox and cell phone number _java

The main use of Java.util.regex class.

Copy Code code as follows:

Import Java.util.regex.Matcher;

Import Java.util.regex.Pattern;

public class Checkmobileandemail {

/**

* Verify that the mailbox address is correct

* @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]+)? \ n.) +[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 mobile phone number

* @param mobiles

* @return [0-9]{5,9}

*/

public static Boolean Ismobileno (String mobiles) {

Boolean flag = false;

try{

Pattern p = pattern.compile ("^ (13[0-9]) | (15[^4,\\d]) | (18[0,5-9)) \\d{8}$");

Matcher m = p.matcher (mobiles);

Flag = M.matches ();

}catch (Exception e) {

Flag = false;

}

return flag;

}

public static Boolean Isnum (String number) {

Boolean flag = false;

try{

Pattern p = pattern.compile ("^[0-9]{5}$");

Matcher m = p.matcher (number);

Flag = M.matches ();

}catch (Exception e) {

Flag = false;

}

return flag;

}
