Map接口的hash表+链表实现(有可预测的iterator顺序); LinkedHashMap是双向链表; This linked list defines the iteration ordering, which is normally the order in which keys were inserted into the map (<i>insertion-order</i>). 定义了iterator顺序,一般是 插入顺序; Note that insertion order is not af...
LinkedHashMap<String, Integer> map = new LinkedHashMap<>(); // 假设map已经被填充 List<String> keys = new ArrayList<>(map.keySet()); 将值转换为列表:类似地,如果您只需要值,可以使用values()方法。 java List<Integer> values = new ArrayList<>...

This implementation differs from HashMap in that it maintains a doubly-linked list running through all of its entries. This linked list defines the iteration ordering, which is normally the o...

This linked list defines the encounter order (the order of iteration), which is normally the order in which keys were inserted into the map (insertion-order). The least recently inserted entry (the eldest) is first, and the youngest entry is last. Note that encounter order is not affected...

In this example, we first create aLinkedHashMapwith string keys and integer values. Then, we convert the map to a list of key-value pairs using thetoListfunction. Next, we sort the list using thesortedWith()function and provide a comparator. Finally, we create a newLinkedHashMapusing the...
