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...
Similarly, we can iterate through theMapusing anIteratorandkeySet(): publicvoiditerateUsingIteratorAndKeySet(Map<String, Integer> map){ Iterator<String> iterator = map.keySet().iterator();while(iterator.hasNext()) {Stringkey=iterator.next(); System.out.println(key +":"+ map.get(key)); } ...
