concatenate "List" values to String as csv

Question

I have some values in List<SelectItem> selectedDividendYears
Now I want to make a string concatenating all the values of this list as csv.

For Example:

selectedDividendYears = {'123', 'sdf234', '12 1234c'}

now I want only one string, which will look like -

"123, sdf, 12 1234c"

It would appear so. join has many different variations: http://commons.apache.org/lang/api-2.5/org/apache/commons/lang/StringUtils.html#join%28java.util.Collection,%20char%29 – Jeremy Goodell May 26 '12 at 08:55

StringBuilder str = new StringBuilder();
boolean first = true;
for (SelectItem item : selectedDividendYears) {
   if (first) first = false;
   else str.append(",");
   str.append(item.toString());
}

String outputString = str.toString();
