Advanced Java: Exploring Custom Annotations and Processing

Annotations in Java are a way to provide metadata for your code. They are a powerful mechanism for attaching supplementary information to your classes, methods, variables, or other elements of your code. You can use built-in annotations provided by Java, such as @Override, @Deprecated, or @SuppressWarnings, or you can create your own custom annotations. Annotations can be processed at compile-time or runtime, depending on their type and usage.

This code example demonstrates how to create and use a custom annotation called "MyAnnotation". The annotation can be applied to both classes and methods. The "Example" class and its "annotatedMethod" are annotated with "MyAnnotation". The main method simply calls the "annotatedMethod".
