Java TreeSet：基于红黑树的排序集合解析

在Java集合框架中，TreeSet是一个有序的、不允许元素重复的集合。它基于红黑树（Red-Black Tree）数据结构实现，这种数据结构能够确保元素在插入、删除后仍然保持有序状态。红黑树是一种自平衡的二叉查找树，它通过一系列的旋转和颜色调整来保证树的高度相对较低，从而保证了操作的效率。一、T...

【JavaSE专栏52】Java集合类TreeSet解析，基于红黑树实现的有序非重集合

一、什么是TreeSet在 Java 中，TreeSet 是基于红黑树实现的有序集合，它实现了 SortedSet 接口。TreeSet 中的元素按照自然顺序（或者根据自定义的比较器）进行排序，并且不允许存储重复元素。TreeSet 的特点有如下 6 66 点，请同学们认真学习。有序性：TreeSe...
