Enum Inside Class

Question

I am trying to define an enum within a class but Eclipse continues to underline my code in the lovely red color. Here is what my code looks like for the most part:

package campusvilleFoodBank;

import java.util.NoSuchElementException;
import java.util.Scanner;

public class FoodArrayList {

    public enum Days {SUN, MON, TUE, WED, THUR, FRI, SAT}

    private Food [] foodArray;
    private int iterator;
    private boolean startIndexing;
    private static final int MAX = 24;

    public FoodArrayList(){
        foodArray = new Food [MAX];
        iterator = 0;
    }

    public FoodArrayList(int arraySize){
        foodArray = new Food [arraySize];
        iterator = 0;
    }
//Rest of code, with more complicated methods here
}

I must be missing something very simple, it's likely to be a syntax error.... The code that follows involves methods such as my toString(), some sorting methods for the foodArray instance variable, and things along those lines. I do not have a main method defined. I know that I can define an enum within a class definition and all of the code I've seen elsewhere is written nearly exactly the same as to what I have. However, Eclipse does not seem to recognize even the enum declaration and I don't believe I need to import anything.

Here is what I see in Eclipse for the code I have an error with:

For comparison, here is some enum code from another, separate .java file that appears to be without error:

Any assistance on this would be appreciated. Let me know if further clarification is needed.

Don't you have more of an error message than "underlines in red"? Are you just missing a semicolon after the enum declaration? — Robert, Dec 27 '15 at 00:18

It could be a couple of things but not related to enum, this is fine.

Seems to me that unless Food does exist, it MUST be created
If it does exist, then it must reside in a different package, which in turn you have to import it like this

import package_name.package2.Food;
It could be that your class name is not identical to you file name

FoodArrayList
Sometimes your IDE in this case Eclipse needs some help, try saving the file, closing it and opening it back up.

Food is another class outside of FoodArrayList – coolDude Dec 27 '15 at 01:12
¿Is it inside of the same package: `campusvilleFoodBank` ? if not the **import** – Esteban Rincon Dec 27 '15 at 01:14
When you hover over the underlined errors. ¿What error message do you get? – Esteban Rincon Dec 27 '15 at 01:14
They are both within the same package – coolDude Dec 27 '15 at 01:14

Seems like you could have an old version of JRE, take a look at this: – Esteban Rincon Dec 27 '15 at 01:25

you have a semicolon missing at the end of the enum in the FoodArrayList class

He doesn't semi-colons are only required in enum definitions if they also contain implementation – Mark Rotteveel Jul 20 '17 at 20:21
