Use StringBuilder instead may do your a favor.This is snippet is copied from AbstractCollection.toString(),take a look at it.

 public String toString() {
    Iterator i = iterator();
if (! i.hasNext())
    return "[]";

StringBuilder sb = new StringBuilder();
sb.append('[');
for (;;) {
    E e = i.next();
    sb.append(e == this ? "(this Collection)" : e);
    if (! i.hasNext())
    return sb.append(']').toString();
    sb.append(", ");
}
}
