I want to avoid getting ConcurrentModificationException. How would I do it?

推荐答案

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(...));
    }
}
