java - iterator.remove() 在 Java 中的所有情况下是否都可靠？

Question

因为在 C++ 中 iterator.remove() 不是 100% 安全或健壮的Java 是否通过 iterator.remove() 保证 100% 的健壮性？

Answer 1

脱离马特的评论(谁真正值得称赞)

http://java.sun.com/javase/6/docs/api/java/util/Iterator.html#remove%28%29

说:

void remove()

Removes from the underlying collection the last element returned by the iterator (optional operation). This method can be called only once per call to next. The behavior of aniterator is unspecified if the underlying collection is modified while the iteration is in progress in any way other than by calling this method.

所以......是的，在某些情况下可能会发生意外/不安全的行为。
