Search array list for substring

Question

Let say I have an array list with names and the names are stored like this...

    John(2), 
    Bob(anytext), 
    Rick

I'm trying to iterate over my array list and check for "(" basically and just take the rest of the string behind it and return that as a string, and null if nothing there. I've seen methods to do similar things but I can't seem to find something to just return the rest of the string if it finds the "("

for(int i=0; i<list.size(); i++) {
  String s = list.get(i);
  int x = s.indexOf('(');
  if(x==-1) break;
  return s.substring(x+1);
}

Pass the strings you want to check to a method that does something like this:

        if(str.contains("(")){
           return str.substring(str.indexOf("("));
        }else{
            return null;
        }

Java 8 version

List<String> list = Arrays.asList("John(2)", "Bob(anytext)", "Rick");
String result = list.stream()
        .filter(x -> x.contains("("))
        .findFirst()
        .map(x -> x.substring(x.indexOf("(")))
        .orElse(null);
