Java 集合之TreeSet 自定义类 比较器 Java 集合之TreeSet 基于TreeMap 的 NavigableSet 实现。 使用元素的自然顺序进行排序,或者通过在集合创建时提供的 Comparator 进行排序,具体取决于使用的构造函数。唯一,无序(没有按照输入顺序进行输出)又有序(按照升序进行遍历)。 此实现为基本操作(添加、删除和包含)提供有保...
Java集合是Java编程语言中用于存储和操作数据的一组类和接口。它们提供了各种数据结构和算法,以便开发人员可以方便地处理和操作数据。 Java集合框架包括了多种类型的集合,其中之一就是Java集合中的"TreeSet"和"TreeMap"。TreeSet是基于红黑树实现的有序集合,而TreeMap是基于红黑树实现的有序映射。 TreeSet是一个有序...

参见: [JDK-In-Action-TreeMap] 这个实现提供的基本操作(add, remove,contains)保证log(n)时间开销. 和TreeMap一样,该集合也是非线程安全的,快速失败的.提供的Key需要是可比较的. API Example 构造函数之 Tree Set 1 2 3 4 5TreeSet<Integer> src =newTreeSet<>((o1, o2) -> o2 - o1); ...
Java有效地存储了大量排序数据 、、、 通常,当我想在java中存储大量数据时,我会使用Set<String>,这是非常快速和高效的。 Set<String> example = new HashSet<String>(); 但问题是它不能被排序。我不能使用Lists,因为我要存储非常大量的数据(100,000),而使用List会严重影响我的程序性能。 ArrayList<String> ...
