java regex for iraq phone number

Question

I need a regex to match this phone number pattern:

• it always starts with 07
• then it is followed by a number from this range (3-9)
• and it must be 11 chars

example : 07902848117

07796938209

07302819248

Answer 1

Try this, it should work.

"07[3-9][0-9]{8}"  

What this mean is,   
07 - it tries to find literally 07  
[3-9] - then followed by 3 to 9, only one time
[0-9] - then followed by 0 to 9  
{8} - text previous to this should has at least 8 characters.
