Java Common Regular Expression validation tool class Regexutils.java_java

Regular expressions are often used to validate various forms, Java forms register common Regular Expression validation tool classes, and common regular expression large collections.

1. Telephone number

2. zip Code

3. QQ

4. E-Mail

5. Mobile phone number

6. URL

7. Whether it is a digital

8. Whether it is Chinese

9. Identity card

10. Domain Name

IP .....

Common validation Everything! This is indeed your work in Web development, server-side form verification of good products! You deserve to have ^_^
