I am trying to take
scjp 6 exam in coming Feburary. When I took one question about group()of matcher class,my answer is wrong.That question is like that...
java Regex2 "\d*" ab34ef
Answer is E.01234456
why ?this answer get? i think is it will get 234.and I know is that group(0)return whole
string,and i don't know group()without parameter how it works?
Thanks.
