Re^2: avoiding a particular character or set of characters

cant i have a solution like

$str ="check this out";
[download]

if this sentence has out do not replace it

if($str =~ s#check this [^out]#check this one#){
}
[download]

is there some way to achieve this
one more thing i am not traversing line by line.
the whole java file i am taking as a single line
using undef $/;

Hi neeha, you cannot use character class here, rather you have to use negative look head. change `if($str =~ s#check this [^out]#check this one#){ }` [download] into `$str ="$str ="check this out check this here";"; $str =~ s#check this ((?!out).)+#check this one#gs; print $str;` [download] Prasad	[reply] [d/l] [select]

my problem is `/** * public void method1(); * is deprecated / public void method1();` [download] in this case my code replaces to `/* * replaced code */ public void method1();` [download] It dont want to replace anything in the comments and my code reads the entire java file as a single line.
