I'll need some help on that one to make the compiler work!

Question about the task

Implement annotations

Java Collections, Level 8, Lesson 10

Under discussion

It seems like I can't have a default value for enum field, or is it something else making the program not compile?

The project must compile and display the Solution class's annotation.
Don't change the Solution class or its annotation.
The Changelog annotation must be visible at runtime.

Requirements:

The screen output must match the expected output.
The Solution class's @Changelog annotation must be displayed.
The @Changelog annotation must be visible at runtime.
The Solution class must implement a main method with one String[] parameter.

package com.codegym.task.task38.task3810; import java.lang.annotation.ElementType; import java.lang.annotation.Target; @Target(ElementType.FIELD) public @interface Date { int year() default 0; int month() default 0; int day() default 0; int hour() default 0; int minute() default 0; int second() default 0; }

One of problem is in `Changelog` class: revision() should be value()

@Retention(value = RetentionPolicy.RUNTIME)
public @interface Changelog {
    Revision[] value();
}

If you want to pass the test, you should remove all default part from `Date.java` and change the `Author.class` to:

public @interface Author {
    String value();
    Position position() default Position.OTHER;
}

1. In the Author class you are missing a default value for position 2. In the Changelog class you have to return an array of Revision, also the method must be called value(); 3. Not sure about this one but I don't think the @Target annotations that you have added to some interfaces are neccessary
