Java 如何创建一个好用的枚举类

话不多说，直接上代码：

public enum MarryStatusEnum {

    /**
     * 单身
     */
    SINGLE("single", "单身"),
    /**
     * 已婚
     */
    MARRIED("married ", "已婚");


    private final String value;

    private final String name;

    private static Map<String, MarryStatusEnum> valueMap = new HashMap<>();

    static {
        Arrays.stream(MarryStatusEnum.values()).forEach(e -> valueMap.put(e.value, e));
    }

    MarryStatusEnum(String value, String name) {
        this.value = value;
        this.name = name;
    }

    public static MarryStatusEnum of(String code) {
        return valueMap.get(code);
    }

    public String valueName() {
        return this.name;
    }

    public String value() {
        return this.value;
    }

    @Override
    public String toString() {
        return "type{" +
                "value='" + value + '\'' +
                ", name='" + name + '\'' +
                '}';
    }
}
