i need to make a program where the input file is a source code with comments and output is the same code without comments.
It would be perfect if it would eliminate the /* */ comments also.

to solve your problem you'll have to user preg_replace
$notCommentedFile = preg_replace('/#.*/', '', $commentedFile);
$notCommentedFile = preg_replace('#//.*#', '', $notCommentedFile);
$notCommentedFile = preg_replace('#/\*(?:[^*]*(?:\*(?!/))*)*\*/#', '', $notCommentedFile);
this 3 pattern will remove the comment on your file ^^
UPDATE
ups! didn't see the comment X/ this works for php, but i think a java function like preg_replace exist and regular expression are universal :D
here an example on how to use the equivalent preg_replace in java What is the Java equivalent to this preg_replace?
