What is metaprogramming in Java?

Metaprogramming in Java refers to the ability of a program to treat other programs as its data. It allows developers to write code that can manipulate or generate other code at runtime.

Can you give me an example of metaprogramming in Java?

Sure! One common example is using reflection to inspect classes, methods, and fields at runtime. For instance, you can use Class.forName() to load a class and then use getDeclaredMethods() to list its methods.

What are the benefits of using metaprogramming?

The benefits include increased flexibility, reduced code duplication, and the ability to create more dynamic and reusable code components.

Are there any downsides to metaprogramming?

Yes, metaprogramming can lead to code that is harder to understand and maintain. It may also introduce performance overhead due to the dynamic nature of the code.
