Mastering Java: The Ultimate Quiz for 'Thinking in Java'

What is a potential benefit of using a proxy for a null Robot?

1. Increasing the execution speed of the application

2. Facilitating the implementation of complex algorithms

3. Eliminating the need for inheritance

4. Simplifying the management of null cases in the application

The correct answer is: Simplifying the management of null cases in the application

Using a proxy for a null Robot can provide a benefit by simplifying the management of null cases in an application. This is because a proxy object can handle null values and return default values or handle exceptions, making it easier to handle and prevent errors in the code. In contrast, choosing options A, B, or C would not address the issue of handling null cases and could potentially introduce other problems in the application. For example, option A may not necessarily increase execution speed if the null case still needs to be accounted for. Option B may not be directly related to handling null cases, and option C is incorrect as it is not a primary benefit of using a proxy for a null Robot.
