I want to avoid getting ConcurrentModificationException
. How would I do it?
您可以使用 ListIterator
,它在迭代过程中支持删除/添加方法.
You may use a ListIterator
which has support for a remove/add method during the iteration itself.
ListIterator<Book> iter = books.listIterator();
while(iter.hasNext()){
if(iter.next().getIsbn().equals(isbn)){
iter.add(new Book(...));
}
}
这篇关于Java - 在迭代时将元素添加到列表中的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持html5模板网!
