想问下在哪调用的Iterator，不是只调用了add吗

#2 Created at ... [Delete] [Delete and Lock User]

这里：

 for (String s : rlist) {
     System.out.println(s);
 }

这里的for循环语句称为foreach语句，是根据iterator来实现的，相当于：

for (Iterator<String> it_s = rlist.iterator; it_s.hasNext(); ) {
   System.out.println(it_s.next());
}

#3 Created at ... [Delete] [Delete and Lock User]

抱歉，

Iterator<String> it_s = rlist.iterator;

应改为

Iterator<String> it_s = rlist.iterator();
