Example of using a Java regular expression to determine a mobile phone number

Therefore, we need to clarify how many number segments have been opened. The country number segments are allocated as follows:

Mobile: 134, 135, 136, 137, 138, 139, 150, 151, 157 (TD), 158, 159, 187, 188

China Unicom: 130, 131, 132, 152, 155, 156, 185, 186

China Telecom: 133, 153, 180, 189 (1349 Weitong)

Now we can test the regular expression matching,

Import java. io. IOException;

Import java. util. regex. Matcher;

Import java. util. regex. Pattern;

Public class ClassPathResource {

Public static boolean isMobileNO (String mobiles ){

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

Matcher m = p. matcher (mobiles );

System. out. println (m. matches () + "---");

Return m. matches ();

}

Public static void main (String [] args) throws IOException {

System. out. println (ClassPathResource. isMobileNO ("12016155153 "));

}

}

Method 2:

Import java. util. regex. Matcher;

Import java. util. regex. Pattern;

String value = "mobile phone number ";

String regExp = "^ [1] ([3] [0-9] {1} | 59 | 58 | 88 | 89) [0-9] {8} $ ";

Pattern p = Pattern. compile (regExp );

Matcher m = p. matcher (value );

Return m. find (); // boolean

Method 3:

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 the 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 [-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;

}

}
