The details are as follows:

/ * determine whether the string conforms to the mobile number format * Mobile number segment: 1341351371381381391471501152157159170183184187188 * Unicom segment: 130131132145155156170175176185186 * Telecom segment: 133149153173177181181189 * @ param str * @ return string to be tested * / public static boolean isMobileNO (String mobileNums) {/ * determine whether the string conforms to the mobile number format * Mobile segment: 1341351361371381381391471501152157159178172184187188 * Telecom segment: 1301132145155176176175185185186 * Telecom number range: 133149153170173177180181189 * @ param str * @ return string to be tested * / String telRegex = "^ ((13 [0-9])) | (14 [5prime7] 9]) | (15 [^ 4]) | (18 [0-9]) | (17 [0meme 1meme 3rem 5je 7je 8]))\\ d {8} $" / / "[1]" represents the first digit is the number 1, "[358]" represents the second digit can be one of 3, 5, 8, and "\ d {9}" represents a number that can be 0,9. If (TextUtils.isEmpty (mobileNums)) return false; else return mobileNums.matches (telRegex);}

"^ (13 [0-9])) | (14 [5magee 7pr 9]) | (15 [^ 4]) | (18 [0-9]) | (17 [0primel, 1meme, 3pr, 6pr, 7pr 8]))\ d {8} $" is actually very simple:

The first three digits of ① 130139 have all been opened, and each of the last eight digits is any number between 0 and 9.

At present, there are only 145,147,149 digits at the beginning of ② 14, and each of the last 8 digits is any number between 0 and 9.

The third digit at the beginning of ③ 15 is optional except 154.Each of the last eight digits is any number between 0 and 9.

The first three digits of ④ 180-189have all been opened, and each of the last eight digits is any number between 0 and 9.

At present, there are 170,171,173,175,176,177,178 at the beginning of ⑤ 17, and each of the last eight digits is any number between 0 and 9.

These regular expressions are only judged at the front end, and in the actual development, the data will still be passed to the background, and the background will judge whether the 11-digit number is a mobile phone number in the database. We write this in order to filter some of the most basic numbers. Make sure that the number entered is 11 digits, and there are some 11 digits that do not seem to be mobile phone numbers.
