What are the different types of annotations in Java?

In Java, annotations are classified into three main types: marker annotations, single-value annotations, and multi-value annotations.

Can you explain what marker annotations are?

Marker annotations are annotations that do not have any elements. They are used to mark a class or method with a specific property, like @Override.

What about single-value annotations?

Single-value annotations have one element. For example, @SuppressWarnings is a single-value annotation that takes a string as its value.

And multi-value annotations?

Multi-value annotations can have multiple elements. An example is @Schedule, which can define multiple scheduling parameters.
