假如有一个未知类型，枚举可以走default判断吗？

[何时丢掉菜鸟称号]

系统做对接，2个系统字典不一致，有时候还有些脏数据，转换时容易出错，有没有办法在其他情况下使用default

    /**
     * 常住类型
     */
    public enum Household {
        household_01(1, "户籍"),
        household_02(2, "非户籍");

        private int index;
        private String name;

        Household(int index, String name) {
            this.index = index;
            this.name = name;
        }

        public int getIndex() {
            return index;
        }

        public String getName() {
            return name;
        }

        private static final Map<Integer, Household> lookup_int = new HashMap<>();

        static {
            for (Household e : EnumSet.allOf(Household.class)) {
                lookup_int.put(e.getIndex(), e);
            }
        }

        public static Household find(int index) {
            Household value = lookup_int.get(index);
            if (value == null) {
                return null;
            }
            return value;
        }
    }
