Java uses regular expressions to determine mobile phone numbers

This article describes how Java uses regular expressions to judge mobile phone numbers. Share with you for your reference, as follows:

To match the mobile phone number more accurately, it is not enough to match only 11 digits. For example, there is no number segment starting with 144,

Therefore, it is necessary to clarify how many number segments have been opened. The distribution of national number segments is as follows:

Mobile: 134, 135, 136, 137, 138, 139, 150, 151, 157 (TD), 158, 159, 187, 188 Unicom: 130, 131, 132, 152, 155, 156, 185, 186 Telecom: 133, 153, 180, 189, (1349 SATCOM)

So now you can do the regular matching test,

The second method:
