Alternatively, we can first get all keys in ourMapusing thekeySetmethod and then iterate through the map by each key: publicvoiditerateUsingKeySetAndForeach(Map<String, Integer> map){for(String key : map.keySet()) { System.out.println(key +":"+ map.get(key)); } } 3.3. Iterating O...
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“迭代式开发”(Agile迭代)要求分阶段交付功能,体现逐步优化的核心逻辑。这...
