How can I prompt a user in Java to input a day of the week with the days in an enum output the response I want

Question

I'm learning java and I got stuck at a question where I need to enter the days of the week into an enum. I then need to put several responses into a switch case statement and have a user enter the day of the week into a JOptionPane and get the program to output the appropriate response.

This is my Enum:

public enum Day {
    SUNDAY, MONDAY, TUESDAY, WEDNESDAY,THURSDAY, FRIDAY, SATURDAY; 
}

This is my attempt at getting the correct response:

public class enumDayMood {
    Day day;
    
    public static void main(String[] args){
        String day = JOptionPane.showInputDialog("Enter the day of the week.");
    }
    
    public void telDayMood(){
        
        Day day = Day.MONDAY;
        
        switch(day){
            case MONDAY:
                JOptionPane.showMessageDialog(null,"Mondays are bad.");
                break;
            case FRIDAY:
                JOptionPane.showMessageDialog(null,"Fridays are better.");
                break;
            case SATURDAY: case SUNDAY:
                JOptionPane.showMessageDialog(null,"Weekends are best");
                break;
            default:
                JOptionPane.showMessageDialog(null,"Midweek days are so-so.");
                break;
        }
    }
    
}

I was able to output every day of the week individually but I can't seem to get the user input to work. I've tried multiple methods but none seem to work.

That seems to work but now my JOptionPane isn't popping up for the responses — Viking-One-Actual, Mar 06 '21 at 14:07
By the way, Java does provide an enum, [`DayOfWeek`](https://docs.oracle.com/en/java/javase/11/docs/api/java.base/java/time/DayOfWeek.html). — Basil Bourque, Mar 06 '21 at 17:41

I suggest using method showOptionDialog rather than showInputDialog. Make each day of the week an option. Then the user just needs to click on the relevant button and that would save him some work, no? Consider the following:

import javax.swing.JOptionPane;

public class WeekDays {
    public enum Day {
        SUNDAY, MONDAY, TUESDAY, WEDNESDAY, THURSDAY, FRIDAY, SATURDAY
    }

    public static void main(String[] args) {
        int index = JOptionPane.showOptionDialog(null,
                                                 "Enter the day of the week.",
                                                 "Moody",
                                                 JOptionPane.DEFAULT_OPTION,
                                                 JOptionPane.QUESTION_MESSAGE,
                                                 null,
                                                 Day.values(),
                                                 Day.MONDAY);
        Day selection = Day.values()[index];
        switch (selection) {
            case MONDAY:
                JOptionPane.showMessageDialog(null,"Mondays are bad.");
                break;
            case FRIDAY:
                JOptionPane.showMessageDialog(null,"Fridays are better.");
                break;
            case SATURDAY: case SUNDAY:
                JOptionPane.showMessageDialog(null,"Weekends are best");
                break;
            default:
                JOptionPane.showMessageDialog(null,"Midweek days are so-so.");
                break;
        }
        System.exit(0);
    }
}

This is how it looks when I run it.

Okay sorry for the late reply, but thanks so much dude that's actually pretty cool. — Viking-One-Actual, Mar 07 '21 at 12:07
