java枚举键值对，以MONDAY(“1”,”星期一”）的形式怎么通过1取到星期一

可以通过遍历枚举类型的所有值，找到对应键值为1的枚举值，然后获取该枚举值对应的星期一字符串。具体代码如下：

enum Weekday {
    MONDAY("1", "星期一"),
    TUESDAY("2", "星期二"),
    WEDNESDAY("3", "星期三"),
    THURSDAY("4", "星期四"),
    FRIDAY("5", "星期五"),
    SATURDAY("6", "星期六"),
    SUNDAY("7", "星期日");

    private String code;
    private String name;

    Weekday(String code, String name) {
        this.code = code;
        this.name = name;
    }

    public static String getNameByCode(String code) {
        for (Weekday weekday : Weekday.values()) {
            if (weekday.code.equals(code)) {
                return weekday.name;
            }
        }
        return null;
    }
}

然后可以通过调用`Weekday.getNameByCode("1")`方法来取得星期一字符串。
