Reflection API · interview question
How can frameworks dynamically map URL routes to private method handlers using Java Reflection?
Multiple choiceMediumchapter-16-curatedpremiumreflection-apibreaking-encapsulation
Method method = handlerClass.getDeclaredMethod("handleRequest");Answer and explanation
Correct answer
B. By invoking methods using 'Method.invoke()'
Why
Frameworks use Reflection's 'Method.invoke()' to dynamically call method handlers, even if they are private, by first setting them accessible. This allows URL routes to be mapped to methods without changing method visibility.
