是否有一种方便的Java8流API方式从List<T> to Map<T, (index)>以下示例进行转换：

    List<Character> charList = "ABCDE".chars().mapToObj(e->(char)e).collect(Collectors.toList());

    Map<Character, Integer> map = new HashMap<>();
    for (int i = 0; i < charList.size(); i++) {
        map.put(charList.get(i), i);
    }

映射= {A = 0，B = 1，C = 2，D = 3，E = 4}
