十四、枚举 enum

public enum WeekDay {
    MONDAY("星期一"),
    TUESDAY("星期二"),
    WEDNESDAY("星期三");
    private final String description;

    WeekDay(String description) {
        this.description = description;
    }

    public String getDescription() {
        return description;
    }
}

public final class com.dto.WeekDay extends Enum<com.dto.WeekDay> {//枚举继承 Enum，所以不能再继承其他类
  public static final com.dto.WeekDay MONDAY;
  public static final com.dto.WeekDay TUESDAY;
  public static final com.dto.WeekDay WEDNESDAY;
  private final java.lang.String description;
  private static final com.dto.WeekDay[] $VALUES;
  public static com.dto.WeekDay[] values();
  public static com.dto.WeekDay valueOf(java.lang.String);//谨慎使用
  private com.dto.WeekDay(java.lang.String);//构造器默认是 private
  public java.lang.String getDescription();
  private static com.dto.WeekDay[] $values();
  static {};
}
