Find all enums in my project

Question

In my project I have a few declared enums. I would like to create a method that loops over all of these and then over all the values of each enum.

Example with two enums:

public enum Mood {
    GOOD, BAD;  
}

public enum Weather {
   WET, DRY;
}

If I looped over each enum and their values and printed them each on a line, the program would print

GOOD
BAD
WET
DRY

The order is not important...

If I add a new enum, that should also be printed without having to change the code. I cannot know in what package the enums will be located. Only a root package.

The Reflections library will help you.

You can search for each class which implements Enum and get all the classes values using clazz.getEnumConstants()
