Regex Password validator

Question

I faced some problem while validating a password that will contain minimum 5 characters using regex.
I am using a very simple regex as below:
String REGEX_PATTERN = "(?=.*[a-z|A-Z]{5,}).{8,}";
It says password must contains minimum 5 characters(a-z|A-Z), and password length will be minimum 8 chars.
It is working fine for the string "aasaT124". But fails for the string "aa12sa4T".
Clearly the difference is regex matches only if the characters are sequential.
The String for which validation fails also contains minimum 5 characters but characters are not sequential.
Pls tell me where is the problem in my regex that introduces this problem. I just need to validate simply whether my string contains minimum 5 characters or not independent of any position or sequence.

The regex pattern should be like below :

it will work.
That does not fulfill the requirements, however.
Yes you are right..
I think this cannot be achieved using regex (not sure) . You can use the javascript function or java method to validate the password.
As I explained in my first response it most definitely can be achieved using a regex. The change to the OP's original regex is almost trivial!
P.S. Why do people think they need to use '|' inside a character class to mean 'or' ?
