遍历Java集合(Arraylist,HashSet...)的元素时,可以采用Iterator迭代器来操作 Iterator接口有三个函数,分别是hasNext(),next(),remove()。 今天浅谈remove函数的作用 官方解释为: Removesfromthe underlying collection the last element returned bythisiterator (optional operation). This method can be called only o...
This method differs from #poll poll only in that it throws an exception if this queue is empty. This implementation returns the result of poll unless the queue is empty. Java documentation for java.util.AbstractQueue.remove(). Portions of this page are modifications based on work created and...

Removes the next reference object in this queue, blocking until either one becomes available or the given timeout period expires. This method does not offer real-time guarantees: It schedules the timeout as if by invoking the Object#wait(long) method. Java documentation for java.lang.ref.Refer...
