推荐答案

可能是因为Iterator中的条目数itr 。可能它只有一个条目。


你能查看实际出现的条目数吗？

It may be because of the number of entries in Iterator "itr". Probably it might have only one entry.

Can you just check on the number of entries actually present?

我检查一下。迭代器有多个元素。但是当i从0变为1而while循环不再迭代时......我认为在i的变化中，while循环应该从开始.....我不知道为什么它会发生..

I check it. Iterator has more than one element. But at the change of i from 0 to 1 while loop is not iterating again......I think at the change of i while loop should start from the begining.....I dont know why its happenin..

v.size（）的chech值，要么这不起作用，要么返回值为1.

或

while（ itr.hasNext（））检查itr.hasNext（）的返回类型，while循环将工作直到condition为true。此条件必须返回布尔值。

chech value of the v.size(), either this is not working or returned value is 1.
or
while(itr.hasNext()) check the return type of the itr.hasNext(), while loop will work till condition is true. This condition must return the boolean value.
