大家好，又见面了，我是你们的朋友全栈君。
I want to have phone number in working combination of ‘0’ followed by 10 digit mobile number (or) 0091 folllowed by 10 digit mobile number (or) 91 followed by 10 digit number.
1) 0 followed and 91 folowed numbers are working with following regex i also want 0091 followed number to be worked, my regex is:
“^([0]|(?:[0][0]|\ )(91))([7-9]{1})([0-9]{9})$”;
Could you suggest me working a regex.

The exact regex you seem to be going for (based on what you’ve tried so far) is:
^(?:0091|\ 91|0)[7-9][0-9]{9}$
Begins with 0, 91 or 0091
Followed by a 7-9
Followed by exactly 9 numbers
No capture groups
Must match entire input
As a general tip, to have worked this out yourself I’d advise using a site like RegExr or RegexPal
Set it to multi-line mode (so that ^ and $ match at the end of each line) then add 0091, 91 and 0 into the input box on separate lines – so you have something like this.
Then try to make a regex that matches just that part, in your case you needed something like
^0091| 91|0$
Note: on RegExr you don’t have to escape backslashes (so when you use the regex in java you need to go through escaping them).
