Arraylist of strings into one comma separated string

Question

Trying to convert a Arraylist of strings into one big comma separated string.

However when I use the

String joined = TextUtils.join(\", \", partici         


        

Answer 1

I don't know what TextUtils does. This will do it.

StringBuffer sb = new StringBuffer();
for (String x : participants) {
    sb.append(x);
    sb.append(", ");
}
return sb.toString();

Easy enough, just use that.
