Question: 1 / 510

Which method in NullRobotProxyHandler is responsible for delegating calls to the proxied object?

newNullRobot

invoke

The method newNullRobot is used to create a new instance of NullRobotProxyHandler, and not specifically for delegating calls. The operations method returns an array of the available proxy methods, but does not specify how the calls are delegated. Option D is incorrect as Java does not automatically handle the delegation of calls to proxied objects. Therefore, the correct answer is option B - invoke. This method takes in the object that is being called, and the method being called, and uses reflection to invoke the call on the original object.
