regex - Quantifier to print only three digit numbers in a Java regular expression -

-

what quantifier print 3 digit numbers in string in java regular expressions?

input : 232,60,121,600,1980 output : 232,121,600

instead output coming as:

output : 232,121,600,198

i using (\\d{3}). quantifier should use in order print 3 digit numbers?

you need make use of \b word boundary:

\b\d{3}\b

see demo

in java, use double slashes:

string pattern = "\\b\\d{3}\\b";

you not need use capturing group round whole regex, can access match via .group(). see ideone demo
