java - Replace last coma and white space with " and "

Question

I'm trying to replace ", " with " and " in a string. I wanna do this with the replaceAll method of String.

Here you can see my try:

String t = "1 hour, 1 minute, 1 second";    
System.out.println(t.replaceAll("/(,\s)(?!.*1)/"," and "));

Expected results:

1 hour, 1 minute and 1 second

But I am getting:

1 hour, 1 minute, 1 second

I'm trying to do the replacement with a regular expression. But it's not working. What is wrong with the regex?
