Answer
Use Method.invoke() on the method. Frame the concept in practical terms so you can explain it during interview discussion.
Reflection can be used to invoke methods dynamically by locating the method with getDeclaredMethod() and calling invoke(). This is useful when the method behavior is determined by its annotations, such as in a plugin framework where methods are annotated with @Plugin.
