如何在 Java 中将字符串数组转换为不同的类 ArrayList

Question

I'm trying to figure out how to write logic to convert an array of string into an ArrayList weekday object

String[] weekdays = request.getParameterValues("weekday");

I've made my ArrayList weekday2 the length of my String[] weekdays.

ArrayList<WeekDay> weekdays2 = new ArrayList<WeekDay>(weekdays.length);

I know there is a way to utilize enums, and that's what I'm trying to do.

for (int i = 0; i < weekdays.length; i++) {
            weekdays2.add(new WeekDay().valueOf(weekdays2, weekdays));
        }

I know I'm definitely missing something.

error:

The method valueOf(Class<T>, String) in the type Enum<WeekDay> is not applicable for the arguments (ArrayList<WeekDay>, String[])

Answer 1

Code to get list of WeekDay may be such:

    for (int i = 0; i < weekdays.length; i++) {
        weekdays2.add(WeekDay.valueOf(weekdays[i]));
    }
