I’ve a string of comma separated user-ids and I want to eliminate/remove specific user-id from a string.

I’ve following possibilities of string and expected result

int elimiate_user_id = 11
String css1 = "11,22,33,44,55" 
String css2 = "22,33,11,44,55" 
String css3 = "22,33,44,55,11" 
//Expected result in all cases, after replacement, should be: "22,33,44,55"

I tried following:

String result = css#.replaceAll("," + elimiate_user_id, ""); // # = 1 or 2 or 3
result = css#.replaceAll(elimiate_user_id + "," , "");

This logic fails in case of css3.

Pl. suggest me proper solution of this issue.
Note: I'm working with Java 7
