java - How to use quantifier regex pattern on blackberry ({m,n}) -

hi im trying write validation class using : regexp-me lib because of reply of post.

what did do

string id = "123456789"; string pattern = "\\d{7,8}"; public boolean validate(string id,string pattern){ re regular_expresion = new re("\\d{7,8}"); homecoming regular_expresion.match(id); }

this code should have returned false "id" since pattern should take 7 8 digits. if utilize id = "1234567" homecoming true , code accepting 7 or more digits.

the {m,n} working {n,}.

has had problem before?

the look \\d{7,8} means:

find anywhere within string a string consisting of digits with @ to the lowest degree 7, not more 8 characters.

this true 1234567 string of 7 digits 123456789 because string contains string 7 or 8 digits.

change look ^\\d{7,8}$ positive result when entire string origin end consists of digits , string length either 7 or 8.
