接下来使用饼状图展示不同类型的集合在某个项目中的使用比例: 40%20%25%15%Collection Type UsageArrayListLinkedListHashSetTreeSet 在饼状图中,我们可以看到在一个假定的项目中,ArrayList使用占比最高,其次是HashSet和LinkedList。 结论 Iterator是Java集合操作中不可或缺的工具,它为我们提供了安全和便捷的遍历方式。

In my previous post, we have already discussed how an Iterator works internally in forwarding Direction at “How Java Iterator Works Internally?” section. Even ListIterator also works in that same way. If you want go through my previous post, please click here:Java Iterator. In this section,...

If there is no error, the status isStatus::OK(). If the status is not OK, the iterator will be invalidated too. In another word, ifIterator::Valid()is true,status()is guaranteed to beOK()so it's safe to proceed other operations without checking status(): ...
Typical usage of iteration in reverse: it := tree.Iterator() for it.End(); it.Prev(); { key, value := it.Key(), it.Value() ... } Other usages: if it.Last() { lastKey, lastValue := it.Key(), it.Value() ... } Enumerable Enumerable functions for ordered containers that im...
