Annotations and Enums
Explore how to use Java reflection to inspect class modifiers, methods, annotations, and enum constants at runtime. This lesson helps you understand dynamic retrieval of metadata, which is essential for building and working with Java frameworks and enterprise applications.
We'll cover the following...
Reflection allows code to inspect class structure and metadata at runtime. This includes inspecting modifiers, methods, annotations, and enum constants. Frameworks use reflection to bind configuration, inject dependencies, and apply rules at runtime.
How can we get a class's modifiers via reflection?
How can we get the methods of a class via reflection?
To see this in practice, let’s write a program that inspects the String class to retrieve its modifiers and declared methods. ...
