TreeMap methods to get keyset and values return Iterator that are fail-fast in nature, so any concurrent modification will throw ConcurrentModificationException. 用于获取键集和值的TreeMap方法返回本质上是快速失败的Iterator ,因此任何并发修改都会抛出ConcurrentModificationException 。 TreeMap in java doesn’...
介绍完了SortedMap,再来回到我们的NavigableMap上面来。 NavigableMap是JDK1.6新增的,在SortedMap的基础上,增加了一些“导航方法”(navigation methods)来返回与搜索目标最近的元素。例如下面这些方法: lowerEntry,返回所有比给定Map.Entry小的元素 floorEntry,返回所有比给定Map.Entry小或相等的元素 ceilingEntry,返回所有比...

This JavaTreeMaptutorial will teach us aboutTreeMapclass, methods, usecases, and other essential details. 1.TreeMapHierarchy in Collection Framework TheTreeMapclass extends theAbstractMapclass and implements theNavigableMapinterface. Here'K'is the type of keys and'V'is the type of mapped values ...
