Iterator 迭代器越界

例子如下：

Iterator i = set.iterator();   while (i.hasNext()) {    System.out.println(i.next());      pw.println(i.next());   }

while(iter.hasNext()) {              ArrayList
     
       undoneUserStoriesList = SprintUtil.getUndoneUserStoriesList(iter.next().getID(),iter.next().getPkey());               if(undoneUserStoriesList.size() >0){                  willdonefeautre--;               }
     

上述错误均是因为两次.next造成的。可修改为

while (i.hasNext()) {    String ss = (String) i.next();    System.out.println(ss);    pw.println(ss);   }

while (iter.hasNext()) {               JIRAFeature jirafeaturetemp = iter.next();               ArrayList
     
       undoneUserStoriesList = SprintUtil.getUndoneUserStoriesList(jirafeaturetemp.getID(),jirafeaturetemp.getPkey());                if(undoneUserStoriesList.size() >0){                   willdonefeautre--;                }
