Question

I want to use regex in my android application to validate some field.

User Name :

1 Capital Letter[A-Z], 2 digit[0-9], 1 Special Character any and then followed by small character[a-z] and lenth would be 10 character max.

Email Address :

Must contain @google.com in last

Mobile :

Must be +91 and after that 10 digit.

How can I form my regex pattern for all three fields..?

Answer 1

Regx for emailid:

^[A-Za-z][A-Za-z0-9]*([._-]?[A-Za-z0-9]+)@[A-Za-z].[A-Za-z]{0,3}?.[A-Za-z]{0,2}$

accepts values as:

• [e-mail]
• [e-mail]
• dv_sdv@fvv
• [e-mail]
• [e-mail]

n etc

Regex for Mobile No:

^[7-9][0-9]{9}$

works perfect for indian mobile numbers.

Regex for landline No:

^[0-9]{3,5}-[2-9]{1}[0-9]{5,7}$

for landline numbers in india with region code

eg: 022-58974658
