Answer 1

in regular expression , a* means a,aa,....,aaaaa...a
u pass some other string other than wild characters like *,?.
the string u want to replace has * at its first place . even though the string has * at some other position like java*sun*com. it will not replace
* with ur specified string. it will treat a* and n* i.e a,aa,aa.. or n,nn,nn....
