Join David Gassner for an in-depth discussion in this video Peeking and polling with queues, part of Advanced Java Programming.
The LinkedList class is one of the many classes in the Collections framework.…It implements an interface called Queue.…These classes typically are used for first- in-first-out or FIFO sorts of operations.…They all support these methods listed in the grid shown here.…You can Insert, Remove, or Examine objects within a queue.…To Insert, you can call add or offer, to Remove, you can call remove or poll, and to Examine,…you can call element or peek.…
The difference between the methods in the second and third columns is that if one of…the methods in the second column fails it will throw an exception, whereas if you call…a method in the third column, and it fails, it will just return some special value and…won't need exception handling.…I'm going to show you how to peek in an object, and how to poll an object, and show you that…when you peek, you're getting a reference to the object but not removing it from the…queue, but when you poll, you both getting the reference and removing it from the queue at the same time.…
