java8 兩個List對象合並和List的轉換成Map

List轉成成Map

public static void main(String[] args) {

        List<String> idList = new ArrayList<>(Arrays.asList("姓名", "性別"));
        List<String> nameList = new ArrayList<>(Arrays.asList("傑克", "男"));

        Map<String,String> listMap = idList.stream().collect(Collectors.toMap(key->key, key->nameList.get(idList.indexOf(key))));
        System.out.println(listMap.toString());
    }


輸出：
{姓名=傑克, 性別=男}
