将两个字符串集合转化为Map

转化为Map肯定用Collertors.toMap();代码如下:

        List<String> keys = Arrays.asList("D","B","C");
        List<String> values = Arrays.asList("value1","value2","value3");
        Map<String, String> collect = keys.stream()
.collect(Collectors.toMap(key -> key, 
v -> values.get(keys.indexOf(v)), (pre, cur) -> cur));
        System.out.println(collect);
