[ArrayListMultimap](http://www.iteblog.com/archives/tag/arraylistmultimap "查看ArrayListMultimap中的全部文章")類的繼承關系如下圖所示：  Guava ArrayListMultimap 　　List[Multimap](http://www.iteblog.com/archives/tag/multimap "查看Multimap中的全部文章")是一個接口，繼承自[Multimap](http://www.iteblog.com/archives/tag/multimap "查看Multimap中的全部文章")接口。ListMultimap接口為所有繼實現自ListMultimap的子類定義了一些共有的方法簽名。ListMultimap接口并沒有定義自己特有的方法簽名，里面所有的方法都是重寫了Multimap接口中的聲明，只是將Multimap接口中返回Collection類型的函數修改成返回List類型。比如Multimap接口中get函數的函數原型為Collection?get(@Nullable K key);而ListMultimap接口則變成了List?get(@Nullable K key);這是因為Multimap接口為多個實現類定義了其子類必須實現的方法，由于其子類（TreeMultimap、[ArrayListMultimap](http://www.iteblog.com/archives/tag/arraylistmultimap "查看ArrayListMultimap中的全部文章")）的實現不一樣，而Multimap接口又定義了它們共有的方法，所以里面的函數原型大多數的返回類型為Collection，我們知道List、Set都繼承自Collection。ListMultimap接口的這種設計符合[《里氏替換法則》](http://www.iteblog.com/archives/696 "里氏替換法則")。 　　AbstractListMultimap繼承自[AbstractMapBasedMultimap](http://www.iteblog.com/archives/tag/abstractmapbasedmultimap "查看AbstractMapBasedMultimap中的全部文章")類，并實現了ListMultimap接口。AbstractListMultimap類中主要實現了ListMultimap接口里面的方法。同ListMultimap接口類似，AbstractListMultimap類將[AbstractMapBasedMultimap](http://www.iteblog.com/archives/tag/abstractmapbasedmultimap "查看AbstractMapBasedMultimap中的全部文章")類中返回Collection類型的函數修改成返回List類型。里面很多的實現都是調用了AbstractMapBasedMultimap類中相應函數的實現，僅僅簡單的將返回Collection類型函數修改為List類型。 　　AbstractMapBasedMultimap類的介紹請參見[《Guava學習之AbstractMapBasedMultimap》](http://www.iteblog.com/archives/701 "Guava學習之AbstractMapBasedMultimap")。 　　[ArrayListMultimap](http://www.iteblog.com/archives/tag/arraylistmultimap "查看ArrayListMultimap中的全部文章")類是Multimap接口的ArrayList方法實現的類，在前面的[《Guava學習之AbstractMapBasedMultimap》](http://www.iteblog.com/archives/701 "Guava學習之AbstractMapBasedMultimap")文章中我們談到了Multimap接口的幾種實現，其中就有以ArrayList實現的。 　　這里說的以ArrayList實現或者TreeSet實現是指key所對應的value存放方式。詳細介紹請看[《Guava學習之AbstractMapBasedMultimap》](http://www.iteblog.com/archives/701 "Guava學習之AbstractMapBasedMultimap") 　　ArrayListMultimap類主要有三個構造函數，實現如下： <table border="0" cellpadding="0" cellspacing="0" style="width: 693px;
