Answer
They allow methods to be discovered and invoked at runtime.
Annotations with RetentionPolicy.RUNTIME can be accessed via reflection to dynamically discover and invoke methods during execution. For example, a mini-framework might scan for methods annotated with a custom @Execute annotation to run specific tasks. This approach is common in plugin systems or frameworks like Spring, where methods are invoked based on their metadata.
