In this post, I decided to compare the performance of different ways to traverse through theHashMapin Java.HashMapis a very widely used class, and most of the time, we fetch the value usingget(Object key)method provided by the class. But it is sometimes required to iterate over the whol...

iterate over:描述遍历操作,如 iterate over a list(遍历列表) iterate through:与数据结构搭配,如 iterate through a HashMap(遍历哈希映射) 四、跨语境对比 日常场景的“迭代”侧重信息的重复传递(如多次提醒),而技术场景的“迭代”需遵循明确的终止条件和步骤控制。例如软件开发中的“迭代式...

This post will discuss how to iterate over a Map in sorted order in Java.1. Use TreeMapThe HashMap in Java provides good performance but doesn’t maintain any order of its elements. If you want insertion-order iteration with near-HashMap performance, you can use LinkedHashMap. If you ...
